The input voltage range is from 3.5V to 36V. The minimum required output capacitance for stable operation is 1μF effective capacitance after consideration of the temperature and voltage coefficient of the capacitor.Output TransistorThe RT9069 builds in a P-MOSFET output transistor which provides a low switch-on resistance for low dropout voltage applications.Error AmplifierThe Error Amplifier compares the internal reference voltage with the output feedback voltage from the internal divider, and controls the Gate voltage of P-MOSFET to support good line regulation and load regulation at output voltage. EnableThe RT9069 delivers the output power when it is set to enable state. When it works in disable state, there is no output power and the operation quiescent current is zero.Current Limit ProtectionThe RT9069 provides current limit function to prevent the device from damages during over-load or shorted-circuit conditions. This current is detected by an internal sensing transistor.Over-Temperature ProtectionThe over-temperature protection function turns off the P-MOSFET when the junction temperature exceeds 150︒C (typ.) and the output current exceeds 4mA. Once the junction temperature cools down by approximately 20︒C, the regulator automatically resumes operation.RT9069Absolute Maximum Ratings (Note 1)●VCC, EN to GND ---------------------------------------------------------------------------------------------------- -0.3V to 40V●VOUT to VCC -------------------------------------------------------------------------------------------------------- -40V to 0.3V●VOUT to GNDRT9069-90/RT9069-C0 ------------------------------------------------------------------------------------------- -0.3V to 15V RT9069-25/RT9069-30/RT9069-33/RT9069-50 ------------------------------------------------------------ -0.3V to 6V●Power Dissipation, P D @ T A= 25°CSOP-8 (Exposed Pad) ---------------------------------------------------------------------------------------------- 3.26WSOT-23-5 ------------------------------------------------------------------------------------------------------------- 0.45WSOT-89-5 ------------------------------------------------------------------------------------------------------------- 0.87WUDFN-6L 1.6x1.6 --------------------------------------------------------------------------------------------------- 2.15W●Package Thermal Resistance (Note 2)SOP-8 (Exposed Pad), θJA--------------------------------------------------------------------------------------- 30.6°C/W SOP-8 (Exposed Pad), θJC--------------------------------------------------------------------------------------- 3.4°C/W SOT-23-5, θJA-------------------------------------------------------------------------------------------------------- 218.1°C/W SOT-23-5, θJC-------------------------------------------------------------------------------------------------------- 28.5°C/W SOT-89-5, θJA -------------------------------------------------------------------------------------------------------- 113.9°C/W SOT-89-5, θJC ------------------------------------------------------------------------------------------------------- 6.9°C/W UDFN-6L 1.6x1.6, θJA --------------------------------------------------------------------------------------------- 46.5°C/W UDFN-6L 1.6x1.6, θJC --------------------------------------------------------------------------------------------- 18.6°C/W●Lead Temperature (Soldering, 10 sec.) -------------------------------------------------------------------------260︒C●Junction Temperature -----------------------------------------------------------------------------------------------150︒C●Storage Temperature Range --------------------------------------------------------------------------------------- -65︒C to 150︒C ●ESD Susceptibility (Note 3)HBM (Human Body Model) ---------------------------------------------------------------------------------------- 2kV Recommended Operating Conditions (Note 4)●Supply Input Voltage --------------------------------------------------------------------------------------------------3.5V to 36V●Junction Temperature Range --------------------------------------------------------------------------------------- -40︒C to 125︒C ●Ambient Temperature Range---------------------------------------------------------------------------------------- -40︒C to 85︒C Electrical Characteristics(C = 1μF, T= 25︒C, for each LDO unless otherwise specified)RT9069Note 1.

The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula :P D(MAX) = (T J(MAX) - T A) / θJAwhere TJ(MAX)is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125︒C. The junction to ambient thermal resistance, θJA, is layout dependent. For SOP-8 (Exposed Pad) packages, the thermal resistance, θJA, is 30.6︒C/W on a standard JEDEC 51-7 four-layer thermal test board. For SOT-23-5 package, the thermal resistance, θJA, is 218.1︒C/W on a standard JEDEC 51-7 four-layer thermal test board. For SOT-89-5 package, the thermal resistance, θJA, is 113.9︒C/W on a standard JEDEC 51-7 four-layer thermal test board. For UDFN-6L 1.6x1.6 package, the thermal resistance, θJA, is 46.5︒C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A= 25︒C can be calculated by the following formula : P D(MAX) = (125︒C - 25︒C) / (30.6︒C/W) = 3.2679W for SOT-8 (Exposed Pad) packageP D(MAX) = (125︒C - 25︒C) / (218.1︒C/W) = 0.4585W for SOT-23-5 packageP D(MAX) = (125︒C - 25︒C) / (113.9︒C/W) = 0.8779W for SOT-89-5 packageP D(MAX)= (125︒C -25︒C) / (46.5︒C/W) = 2.15W for UDFN-6L 1.6x1.6 package The maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX)and thermal resistance, θJA.

Basic spec commands for a diffraction experimentDonald A.WalkoBeamline7ID,Advanced Photon Source,Argonne National Laboratory,Argonne,IL60439***************January18,2016AbstractThis document lists some common commands(plus a few other hints)for casual users of the diffrac-tometer control program spec.This is meant to briefly list common ways to use some of the most usefulcommands,not to be an exhaustive list nor a complete description of a command’s syntax.Refer to thespec manual or helpfiles for additional information[1],such as the structure of datafiles,setting motorpositions or software limits,plotting and printing scans,and geometry-specific macros.The beamlinestaffmay also be able to help with these issues,and probably should be consulted before users makesignificant changes such as resetting a motor’s position or soft limits.Starting SPECFrom your local beamline contact,determine how to log in to the appropriate computer to run spec, open any xterminal that may be necessary,and start the spec program.Typically,the program name is the geometry name,such as fourc,kappa,or psic.The basic SPEC commandsspec is a command-line based program.Therefore it is important to know the correct commands; fortunately,some commands will list the type of parameters needed if you enter the wrong type(or number) of parameters.Actually,most“commands”(and many variables)are actually macros and could be redefined, which is not something one should normally do.But the writing and implementation of new macros is quite straightforward;users often write shortcut macros which are combinations of a number of commands.It is also important to note that spec is case-sensitive;most commands and variable names are lower-case,while certain special variables and macros are upper-case.“Information”commandspaI still don’t know if this stands for“parameters”or“print all,”but it is a very useful way to listparameters such as the orientation matrix,lattice parameters,operating mode,wavelength,etc.whwhere;lists positions of the diffractometer motors(in user units;see below),reciprocal lattice coordi-nates,and some relevant angles.wawhere all;lists positions of all the spec motors(in user and dial units;see below).wm motor name(s)where motor;lists where the motor is(user and dial units)and its software limits.lm[motor name(s)]limits;same as wm,except lm will list all motors if none are specified.1p some expressionprint;can be used to print a variable’s value:p F CHIor as a calculator:p5*sin(PI/4)helpcalls the spec help utility,and lists a sizable number of topics which are described to varying degrees of detail.The following commands may be more helpful for advanced users:prdef macro nameprint definition;prints the definition of a macro.lsdeflist defined;lists the names and sizes of all currently defined macros.lscmdlist command;lists built-in commands and functions.whats somethingidentifies an object,as keyword,function,macro,or variablesyms[name]list of known symbols:all or only those which match name(you may use the wildcard characters*or )Miscellaneous commandsct[time]counts and lists results for all scalers.The counting is for time sec or for the default time if value is omitted(such as1sec).But if value is negative,then counting continues until the monitor reaches value counts.Examples of use:ctct10ct-200000The monitor is typically a scaler keeping track of the incident beam.sleep(time)pauses for time eful,e.g.,if you want walk over to a motor to watch it move.Example:sleep(10);umvr th2startupinitializes a variety of parameters.Includes the following macros,which could also be called directly: newsample:title for scan headersnewfile:begins a new datafilesetscans:sets a few scan optionssetplot[value]:options for plotting.Each option has a number,so you can add them up and include value as a shortcut,once you know which options you want.startgeo:calls geometry-dependent set-up macrosdo commandfilereads commands from a textfile.It’s usually good form for thefile name to have a.mac extension qdo commandfilequiet do;same as do,but doesn’t print the commands to the screen.save[file name]saves numerous parameters to a textfile.Allows you to recover things like the orientation matrix if you want to make temporary e the do or qdo command to read thefile back into spec.2comment"whatever you want to say"writes a time-stamped comment to the datafile.u[unix command]unix shell:executes unix command(if included)or goes to the unix command line.To escape from the unix command line,type exit.Some unix commands are directly accessible without typing the u: cd:change directoryls:list directory contentsl:list directory contents(the unix ls-l command)pwd:present working directoryquitquit out of spec.“exit”does not do this.Be careful to understand the effects of the following commands before executing them.They may,for example,be safe on a simple rotary stage,but not on a more complex diffractometer:set motor name positionsets a motor’s position(in user units).set lm motor name low highsets a motor’s limits(in user units).set dial motor name positionsets a motor’s position(in dial units).configcalls the hardware configuration editor.Allows configuration of motors,scalers,and other devices.These are mostly advanced options which should not be altered casually.Simple motor motionsumv motor name positionmove motor name to absolute position(in user units).Examples:umv th20umv th CENSee below under dscan for information on the variable CEN.umvr motor name rel positionmove motor name by the relative amount rel position from its current position.ubr H K Lmove motors to the reciprocal lattice point(Bragg point)defined by the Miller indices H K Lca H K Lcalculate the motor position for the reciprocal lattice point H K L.It’s a good habit to do ca before ubr,to avoid unexpected motor motions.tw motor name deltatweak;interactive subroutine to move motor name by delta.Once in the subroutine,each time you hit Enter the motor moves by delta.You can change direction with p/n or+/-,and also change delta by entering a new value.Escape by hitting CTRL-C,or some other letter or symbol,followed by Enter.The‘u’in umv,umvr,and ubr stands for‘update;’the motor positions are regularly updated on the screen while they move.This is not required,but is preferable to mv,mvr,and br since it is not obvious from the latter commands when the motion is completed:spec may appear to have hung,since the prompt appears but won’t respond to new commands until the motors are done moving.3Basic scansA main use of spec is to scan motors and collect data.If you are ever unsure of the order of parameters for a certain scan,just type the scan name and spec will list the parameters in order.For all these scans,one enters the number of intervals,which is one more than the number of points. Thus,the step size is(ending point)-(starting point)/intervals.The unit of time is seconds per point if positive,or monitor counts per point if negative.loopscan npts[count time[sleep time]]time-lapse scan:sit at current conditions and count for npts points without moving motors timescan[count time[sleep time]]indefinite time-lapse scan,i.e.,a loopscan with npts=0Motor scansascan motor name start end intervals timeabsolute scan:motor name starts at start and ends at end(in user units).At the end of the scan, motor name stays at end.Example:ascan th57301dscan motor name rel start rel end intervals timerelative(differential)scan:motor name starts at start+current position and ends at end+cur-rent position.At the end of the scan,motor name returns to its previous position.This is the same as a lup(line up)scan.Example:dscan th-11301;umv th CENThe variable CEN(all caps)is calculated after each scan,and is the absolute position of the peak’s center(as given by the FWHM,not the highest position or the center-of-mass).As long as there is a peak in the scan,this is a good way to line up to it.Note that if you typed umvr th CEN or umv phi CEN you could get into big trouble!It may also give weird results if the FWHM couldn’t be calculated from the scan(e.g.,because of a background value higher than50%of the peak value).a2scan motor name1start1end1motor name2start2end2intervals timeabsolute scan of two motors:motor name1starts at start1and ends at end1,while motor name2 starts at start2and ends at end2.a3scan and a4scan operate similarly,d2scan,d3scan,and d4scan are multimotor relative scans.mesh motor name1start1end1intervals1motor name2start2end2intervals2timemotor mesh scan.A scan of motor name1is done for each point of motor name2,all of which is stored as one spec scan.Example:mesh th5750tth1014301In this example,the full scan contains51*31=1581points.resume[n]resumes an aborted scan.If a positive integer n is included,then n points are skipped.If a negative integer is included,then the last n points are repeated.Reciprocal space scanshscan h start h end intervals timelinear scan in reciprocal space along the H axis.The values of K and L during this scan are based on the previous position in reciprocal space,so you may need to use the ubr command tofirst move to the appropriate point.Example:ubr111;hscan.9 1.120-20000kscan k start k end intervals timesame as hscan but along the K axis.lscan l start l end intervals timesame as hscan but along the L axis.4hklscan h start h end k start k end l start l end intervals timelinear scan in reciprocal space along a general direction.For example,if you wanted to scan in some direction along H and K thru the(111)Bragg peak:hklscan.9 1.1 1.20.811201hklmesh Q1start1end1intervals1Q2start2end2intervals2timereciprocal space mesh scan.Q1and Q2are literally H,K,or L.Thus this type of mesh scan is limited to be along the principal axes of reciprocal space.The value of the third reciprocal space coordinate during this scan is based on the previous position in reciprocal space,so you may need to move there first.For example,if you wanted to scan in the H-L plane thru the(111)Bragg peak:ubr.81.9;hklmesh H.8 1.220L.9 1.1201More complicated scans in reciprocal space(e.g.,radially,or along circles)are possible.See the spec manual for details[1].The orientation matrix and other issuesAn important function of spec is as a calculator,for the transformation between diffractometer angles and reciprocal lattice coordinates.The most important aspect of this is the orientation matrix,i.e.,the angular position of the crystal lattice.The basic commands for setting up an orientation matrix are given here,but see the spec manual[1]or your beamline contact for additional information.The orientation matrix is set byfinding two nonparallel Bragg reflections.Since the orientation matrix is never perfect,the primary reflection will exactly agree with the orientation matrix(to a scale factor), but the secondary reflection will not exactly e the commands or0and or1to set the primary and secondary reflections,respectively,if the diffractometer is at the reflection,or use setor0and setor1if you know the appropriate angles but the diffractometer is at some other location.The lattice parameters are set with the setlat command,and the x-ray wavelength is given by the value of the variable LAMBDA.There are three other aspects of determining a unique set of angles for a given(HKL)Bragg point.These vary depending on the particular spec geometry,so are only briefly mentioned here:modes there are generally more diffractometer angles than there are dimensions in reciprocal space(i.e.,3);additional constraint(s)is/are set via the selection of a mode(e.g.,constraining the angle of incidence, or constraining the position of a particular motor).sectors this is how spec selects between sets of angles that are geometrically equivalent.For example,the angle pair(twotheta,omega)is equivalent to(-twotheta,180-omega),but usually one prefers positive values of twotheta.cut points this determines how to break the360◦degeneracy of the circles to avoid wraparound situations.For example,suppose the phi cut point is-180◦,phi is currently at-175◦,and you want to move to -185◦.Then the phi motor will not make a-10◦move but will in fact make a+350◦move to+175◦. User units vs.dial unitsspec maintains an important distinction between the“user units”and“dial units”of a motor.The dial units are the actual values which are read on a motor’s physical dial(when such a dial exists).spec keeps track of a motor’s position using the dial units(for example,in calculating whether a given motion would violate a software limit).Dial units are algebraically converted to user units,which are the units spec uses in calculations such as reciprocal lattice coordinates.As an example,if the detector is positioned to intercept the direct beam but the tick mark on the dial points to90,then tth=0in user units but90in dial units.If you become concerned that a motor has somehow lost its position,you can go into the hutch and read the number offthe dial(if it exists)to compare with the dial units listed in spec.CountersData are recorded by spec via counters(also called scalers).Little will be said here,since so much depends on the particular hardware.Two special scalers are set in the configfile,the timebase(units of seconds)and the monitor.A“ct n”command will count to the timebase if n is positive or to the monitor5if n is negative.Thus,monitor is typically a counter for the incident beam to normalize the signal to the incidentflux.Unfortunately,there is another convention wherein one scaler is called DET and another is called MON; these can be set by giving values to these variables(e.g.,DET=2)or by the command counters.MON is not necessarily the same as the monitor defined above,but I think these counters occupy special columns in the spec datafile.Finally,the relatively new command plotselect lets you choose which counter(s)are plotted on the screen during a scan.References[1]The Certified Scientific Software website has an online manual and help pages for spec at6。
