AP7115
150mA LOW DROPOUT LINEAR REGULATOR WITH SHUTDOWN
Description
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.
