The AP7313 is a 150mA, fixed output voltage, low dropout linear

regulator. The device included pass element, error amplifier,

band-gap, current limit and thermal shutdown circuitry.

The characteristics of low dropout voltage and low quiescent

current make it suitable for low power applications, for example,

battery powered devices. The typical quiescent current is

approximately 65μA.

Built-in current-limit and thermal-shutdown functions prevent IC

from damage in fault conditions.

The AP7313 is available in SOT23 package with different

pin-outs.

Applications
