The APL5320 is a P-channel low dropout linear regulator

which needs only one input voltage from 2.5 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 290mV at 300mA loading.

The APL5320 provides several versions of fixed output

voltages ranging from 1.2 to 3.7V with step 100mV and

2.85V, 4.75V. Current-limit with current foldback and ther-

mal shutdown functions protects the device against cur-

rent over-loads and over-temperature. The APL5320 is

available in SOT-23-5, TSOT-23-5, SOT-23-3, SC-70-5,

VTDFN1.2x1.6-4, and TDFN 1.6x1.6-6 packages.
