AP78LXX SERIES 3-TERMINAL POSITIVE REGULATORS
Description
Pin Assignments
The AP78LXX Series is a three terminal positive regulator
available with fixed output voltages from 5V, 8V and 12V,
making them useful in a wide range of applications. When
used as a Zener diode/resistor combination replacement, the
AP78LXX can improve output impedance by two orders of
magnitude, and lower quiescent current. These regulators
can provide local on card regulation, eliminating the
distribution problems associated with single point regulation.
The voltages available allow the AP78LXX's to be used in
logic systems. Instrumentation, HiFi and other solid state
electronic equipment.

The AP78LXX is available in the plastic TO92, SOT89 and
SO-8 using industrial standard package technology. The
regulator can deliver 100mA output current with adequate
heat sinking. 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
dissipation. Thermal overload protection is integrated to
prevent the IC from overheat due to abnormal condition.

Introduction
The AP78LXX series is a three terminal device with fixed output voltages from 5V,8V and 12V. The AP78LXX fixed voltage
regulator series has built-in thermal overload protection which prevents the device from being damaged due to excessive
junction temperature. The regulator also contains internal short-circuit protection which limits the maximum output current, and
safe-area protection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is
increased.
