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
Features
n LM78L05 in micro SMD package
n Output voltage tolerances of 5% over the temperature
range
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-
