APL5537 Overview
The APL5537 is a dual channel low dropout linear regulator, which operates from 2.5V to 5.5V input voltage and delivers up to 300mA output current at each channel. Typical dropout voltage is only 240mV at 300mA. The APL5537 with low quiescent current, high PSRR, and low noise is ideal for battery powered system appliances.
