General Description
The APL5315 is a P-channel low dropout linear regulator
which needs only one input voltage from 2.7~6V, 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, cellular phones. Typical dropout voltage
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
• Portable and Battery-powered Equipment
• Notebook and Personal Computers
