APL5537 Datasheet PDF - Anpec Electronics

General Description
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. Other features include logic-controlled shutdown mode, over-temperature protection, short-circuit current-limit, and current-limit protection to ensure specified output current. The APL5537 is available in the TSOT-23-6A and TDFN 1.6x1.6-6 packages.
