General Description
The APL5315 is a P-channel low dropout linear regulator which needs only one input voltage from 2.8~6V, and delivers current up to 300mA to set output voltage. It also can work with low ESR ceramic capacitors and is ideal for using in the battery-powered applications such as notebook computers and cellular phones. Typical dropout voltage is only 230mV at 300mA loading.
