General Description
The APL5701/2 is a P-channel low dropout linear regulator which needs only one input voltage from 1.42V to 3.47V, and delivers current up to 700mA 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 notebook computers and cellular phones. Typical dropout voltage is only 75mV at 700mA loading. The APL5701/2 integrates many functions. A POK indicates that the output voltage status with a delay time set internally. It can control other converter for power sequence. TheAPL5701/2 can be enabled by other power systems. Pulling and holding the EN voltage below 0.4V shuts off the output. The functions of thermal shutdown and current-limit protect the device against thermal and current over-loads. The APL5701/2 is available in a SOT-23-5, SOT-23-6, SOP-8P, TDFN3x3-10 and TDFN2x2-8 packages.
