Application Note
(Continued)
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.
