The AP7115 is a 150mA, fixed output voltage, low dropout linear

regulator. The device includes pass element, error amplifier,

band gap reference, current-limit and thermal shutdown circuit.

The characteristics of low dropout voltage and low quiescent

current make it suitable for use in battery powered devices. The

typical quiescent current is approximately 50µA. Several fixed

output voltages are available from 1.0V to 3.5V. Additional

protection

is

provided

with

built-in

current-limit

and

thermal-shutdown functions.
