EITHER ±5%(AC)OR ±10%(C)SELECTIONDESCRIPTIONThe L78L00series of three-terminal positive regulators employ internal current limiting and thermal shutdown,making them essentially indestructible.If adequate heat-sink is provided,they can deliver up to 100mA output current.They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation.In addition,they can be used with power pass elements to make high-current voltage regulators.The L78L00series used as Zener diode/resistor combination replacement,offers an effective output impedance improvement of typically twoorders of magnitude,along with lower quiescent current and lower noise.L78L00SERIESPOSITIVE VOLTAGEREGULATORSL78L00SERIES2/24ABSOLUTE MAXIMUM RATINGS(*)Our SO-8package used for Voltage Regulators is modified internally to have pins 2,3,6and 7electrically communed to the die attach flag.This particular frame decreases the total thermal resistance of the package and increasesits ability to dissipate power when an appro-priate area of copper on the printed circuit board is available for heat-sinking.The external dimensions are the same as for the standard SO-8.THERMAL DATA(*)Considering 6cm of copper Board heat-sinkTEST CIRCUITSCONNECTION DIAGRAM (top

LM78M12中⽂资料LM341/LM78MXX Series3-Terminal Positive Voltage RegulatorsGeneral DescriptionThe LM341and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting,thermal shutdown,and safe-operating area protection which makes them virtually immune to damage from output overloads.With adequate heatsinking,they can deliver in excess of 0.5A output current.Typical applications would include local (on-card)regulators which can eliminate the noise and de-graded performance associated with single-point regulation.Featuresn Output current in excess

fixed voltage regulator series has built-in thermal overload protection which prevents the de-vice from being damaged due to excessive junction tem-perature.The regulators also contain internal short-circuit protection which limits the maximum output current,and safe-area pro-tection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is in-creased.Although the internal power dissipation is automatically lim-ited,the maximum junction temperature of the device must be kept below +125?C in order to meet data sheet specifica-tions.An adequate heatsink should be provided to assure this limit is not exceeded under worst-case operating condi-tions (maximum input voltage and load current)if reliable performance is to be obtained).1.0Heatsink ConsiderationsWhen an integrated circuit operates with appreciable cur-rent,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable per-formance and reliability.This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating envi-ronment.A one-dimension steady-state model of conduction heat transfer is demonstrated in The heat generated at thedevice junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient envi-ronment.Below is a list of variables that may affect the ther-mal resistance and in turn the need for a heatsink.R θJC (Component Variables)R θCA (Application Variables)Leadframe Size &Material Mounting Pad Size,Material,&LocationNo.of Conduction Pins Placement of Mounting Pad Die SizePCB Size

regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM78MXX/LM341XX must be within the range of 0?C to 125?C.A heatsink may be required depending on the maxi-mum power dissipation and maximum ambient temperature of the application.To determine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I GP D =(V IN ?V OUT )I L +V IN I Gshows the voltages and currents which are present in the circuit.The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):θJA =TR (max)/P D If the maximum allowable value for θJA ?C/w is found to be ≥60?C/W for TO-220package or ≥92?C/W for TO-252pack-age,no heatsink is needed since the package alone will dis-sipate enough heat to satisfy these requirements.If the cal-culated value for θJA fall below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of TO-252for different heatsink area.The copper patterns that we used to measure these θJA are shown at the end of the Application Note Section.reflects the same test results as what are in
