LM78LXX SeriesApril 14, 20113-Terminal Positive RegulatorsGeneral DescriptionThe LM78LXX series of three terminal positive regulators isavailable with several fixed output voltages making them use-ful in a wide range of applications. When used as a zenerdiode/resistor combination replacement, the LM78LXX usu-ally results in an effective output impedance improvement oftwo orders of magnitude, and lower quiescent current. Theseregulators can provide local on card regulation, eliminatingthe distribution problems associated with single point regula-tion. The voltages available allow the LM78LXX to be used inlogic systems, instrumentation, HiFi, and other solid stateelectronic equipment.The LM78LXX is available in the plastic TO-92 (Z) package,the plastic SO-8 (M) package and a chip sized package (8-Bump micro SMD) using National's micro SMD package tech-nology. With adequate heat sinking the regulator can deliver100mA output current. Current limiting is included to limit thepeak output current to a safe value. Safe area protection forthe output transistors is provided to limit internal power dissi-pation. If internal power dissipation becomes too high for theheat sinking provided, the thermal shutdown circuit takes overpreventing the IC from overheating.Features■LM78L05 in micro SMD package■Output voltage tolerances of ±5% over the temperaturerange■Output current of 100mA■Internal thermal overload protection■Output transistor safe area protection■Internal short circuit current limit■Available in plastic TO-92 and plastic SO-8 low profilepackages■No external components■Output voltages of 5.0V, 6.2V, 8.2V, 9.0V, 12V, 15V■See AN-1112 for micro SMD considerations Connection DiagramsSO-8 Plastic (M)(Narrow Body)774402Top View8-Bump micro SMD774424Top View(Bump Side Down)(TO-92)Plastic Package (Z)774403Bottom Viewmicro SMD Marking Orientation774433Top View© 2011 National Semiconductor LM78LXX Series 3-Terminal Positive RegulatorsOrdering InformationPackage NSC Drawing Output VoltageOrder Number Supplied As micro SMD BPA08AAB 5V LM78L05IBPX Reel of 3000Thin micro SMDTPA08AAA5V LM78L05ITP Reel of 250LM78L05ITPX Reel of 30009VLM78L09ITPX Reel of 3000SOIC NarrowM08A5VLM78L05ACMRail of 95LM78L05ACMX Reel of 2500LM78L05AIM Rail of 95LM78L05AIMX Reel of 250012V LM78L12ACMX Reel of 250015V LM78L15ACMX Reel of 2500TO-92Z03A5V LM78L05ACZ Box of 18006.2VLM78L62ACZ Box of 18009V LM78L09ACZ Box of 180012V LM78L12ACZ Box of 180015VLM78L15ACZBox of 1800 2L M 78L X X S e r i e sAbsolute Maximum Ratings (Note 1)If Military/Aerospace specified devices are required,please contact the National Semiconductor Sales Office/Distributors for availability and specifications.Power Dissipation (Note 5)Internally LimitedInput Voltage35VStorage Temperature−65°C to +150°CESD Susceptibility (Note 2)1kVOperating Junction Temperature SO-8, TO-920°C to 125°C SO-8 (5V Only)-40°C to 125°C micro SMD−40°C to 85°C Soldering InformationInfrared or Convection (20 sec.)235°CWave Soldering (10 sec.)260°C (lead time)LM78LXX Electrical CharacteristicsLimits in standard typeface are for T J = 25°C, Bold typeface appliesover the entire operating temperature range of the indicated package.
