APL5312

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 36mV_RMS makes it an ideal choice.

Design with an internal P-channel MOSET pass element, the APL5312 maintain a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown protection and current limit protection to ensure specified output current and controlled short-circuit current. The APL5312 regulator come in a miniature SOT23-5 and SC70-5 package.
