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.
