General Description

The APL5312 is a ultra low noise, low dropout linear regulator, which operate from 2.3V to 6V input voltage and deliver up to 300mA. Typical dropout voltage is only 290mV at 300mA loading. Designed for use in RF applications, the high PSRR 74dB and low noise 36mVRMS makes it an ideal choice.
