LM78LXX Series

3-Terminal Positive Regulators

tection for the output transistors is provided to limit internal

power dissipation. If internal power dissipation becomes too

high for the heat sinking provided, the thermal shutdown cir-

cuit takes over preventing the IC from overheating.

General Description

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

n Output current of 100 mA

regulators can provide local on card regulation, eliminating

the distribution problems associated with single point regula-

tion. The voltages available allow the LM78LXX to be used in

logic systems, instrumentation, HiFi, and other solid state

electronic equipment.

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

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 de-

liver 100 mA output current. Current limiting is included to

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

n No external components

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