Fast Transient Response (Continued)

The AP7331’s fast transient response from 0 to 300mA

provides stable voltage supply for fast DSP and GSM

chipset with fast changing load.

Small Overshoot and Undershoot

The AP7331 has small and controlled overshoot and

undershoot in load and line transitions. This helps to

protect supplied circuit from damage and operation error

caused by glitches. This feature also permits the usage

of small value output decoupling capacitor with AP7331.

Low Quiescent Current

The AP7331, consuming only around 65µA for all input

range and output loading, provides great power saving in

portable and low power applications.

Wide Output Range

The AP7331, with a wide output range of 0.8V to 5.0V,

provides a versatile LDO solution for many portable

applications.
