The APL5325 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 APL5325 is available in a SOT-
23-5 package.
