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.
Applications
• Cellular Phones

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).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.
