APL5325
Adjustable Low Dropout 300mA Linear Regulator
Features
General Description
• Wide Operating Voltage: 3~6V
• Low Dropout Voltage:
300mV(Typical) @ 300mA
• Guaranteed 300mA Output Current
• Adjustable Output Voltage: 0.8~5.5V
• Current-Limit Protection with Foldback Current
• Over-Temperature Protection
• Stable with Low ESR Ceramic Capacitor
• SOT-23-5 Package
• Lead Free and Green Devices Available
(RoHS Compliant)
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.
