LM78LXX Series
3-Terminal Positive Regulators
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
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.
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-
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.
