LM78LXX Series

3-Terminal Positive Regulators

General Description

nal power dissipation. If internal power dissipation becomes

too high for the heat sinking provided, the thermal shutdown

circuit takes over preventing the IC from overheating.

The LM78LXX series of three terminal positive regulators is

available with several fixed output voltages making them

useful in a wide range of applications. When used as a zener

diode/resistor combination replacement, the LM78LXX usu-

ally results in an effective output impedance improvement of

two orders of magnitude, and lower quiescent current. These

regulators can provide local on card regulation, eliminating

the distribution problems associated with single point regu-

lation. The voltages available allow the LM78LXX to be used

in logic systems, instrumentation, HiFi, and other solid state

electronic equipment.

n Output current of 100mA

n Internal thermal overload protection

n Output transistor safe area protection

n Internal short circuit current limit

n Available in plastic TO-92 and plastic SO-8 low profile

packages

n No external components

n Output voltages of 5.0V, 6.2V, 8.2V, 9.0V, 12V, 15V

n See AN-1112 for micro SMD considerations

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

technology. With adequate heat sinking the regulator can

deliver 100mA output current. Current limiting is included to

limit the peak output current to a safe value. Safe area

protection for the output transistors is provided to limit inter-
