General Description

The APL5317 is a low dropout linear regulator which only needs a single input voltage supply from 2.8 to 6V, and it can deliver current up to 300mA to a set output voltage. It can work with low ESR ceramic capacitors that make it ideal for using in the battery-powered applications, such as notebook computers and cellular phones.
