Applications

General Description

The APL5315 is a P-channel low dropout linear regulator

which needs only one input voltage from 2.8~6V, and de-

livers 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 230mV at 300mA loading.

The APL5315 provides two kinds of output voltage

operation modes for setting the output voltage. Fixed

output voltage mode senses the output voltage on

VOUT, adjustable output voltage mode needs two

resistors as a voltage divider. Current limit with current

foldback and thermal shutdown functions protect the

device against current over-loads and over temperature.

The APL5315 is available in a SOT-23-5 package.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which

are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for

MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen

free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by

weight).
