Typical Application Circuit
Description
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.
