The AP78L05 is a three terminal positive regulator available with
fixed output voltages. It can be used in a wide range of
applications. It can provide local on-card regulation, eliminating
the distribution problems associated with single point regulation.
The voltages available allow the AP78L05 to be used in logic
system, instrumentation, HiFi, and other solid state electronic
equipments.
The AP78L05 is available in the plastic TO92-3L and SOP-8L
package 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.

Function Description
Introduction
The AP78L05 fixed-mode 5V output voltage regulator is a three terminal device. The AP78L05 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.
