Applications

General Description

The APL5327 is a P-channel low dropout linear regulator

which needs only one input voltage from 3 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 APL5327 is available in a SOT-

23-5 package.
