AP133 FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR

The AP133 is a 300mA, adjustable output voltage, low dropout linear regulator. The device included pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry. The device is turned on when EN pin is set to logic high level. The characteristics of low dropout voltage and less quiescent current make it good for low power applications,.
