General Description 
The uP0111 is a compact fast response low dropout regulator specifically designed to continuously deliver up to 600mA output current. Designed with a P-channel MOSFET series pass transistor, the uP0111 yields extremely low dropout voltage (e.g. 300mV at 600mA) and maintains very low ground current (70uA).
