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.
