Applications

General Description

The APL5324 is a P-channel low dropout linear regulator

which needs only one input voltage from 2.7 to 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 note-

book computers and cellular phones. Typical dropout volt-

age is only 300mV at 300mA loading.

Current limit with current foldback and thermal shutdown

functions protect the device against current over-loads

and over temperature. The APL5324 is available in a SOT-

23-5 package.
