General Description

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 voltage 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 thermal shutdown functions protects the device against current 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.
