General Description

The APL5316 is a low dropout linear regulator which needs only a single input voltage supply from 2.8 to 6V, and it can deliver output current up to 300mA. It can work with low ESR ceramic capacitors and ideally use in the battery-powered applications, such as notebook computers and cellular phones. Its typical dropout voltage is only 170mV at 300mA loading. A power-ok detection indicates the output status at POK pin. The current limit protection (with foldback current) and thermal shutdown functions protect the device against current overloads and over temperature. The APL5316 is available in a SOT-23-5 package.
