APL5507 - 500mA Regulator Reset
The APL5505/6/7 is micropower, low noise , low dropout regulators with a reset function (regulator input (APL5505) or specific voltage(APL5506/7) monitoring), and internal delay circuit, set to detect 3.9V or 4.2V.
Operate from 3V to 6V input voltage and deliver up to 500mA.
Typical output noise is
