Function Description

Introduction

The AP78L12 fixed-mode 12V output voltage regulator is a three terminal device. The AP78L12 fixed voltage regulator series has built-in

thermal overload protection which prevents the device from being damaged due to excessive junction temperature. The regulators also

contain 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.
