3-Terminal Positive Regulators
General Description
The LM78LXX series of three terminal positive regulators is
available with several fixed output voltages making them use-
ful 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 tech-
nology. 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 internal power dissi-

pation. If internal power dissipation becomes too high for the
heat sinking provided, the thermal shutdown circuit takes over
preventing the IC from overheating.

range
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 profile
packages
