GENERAL DESCRIPTION
The ultra-high speed control loop keeps the output voltage within regulation even under extreme transient load swings commonly found in FPGAs and low-voltage ASICs. The output voltage can be adjusted down to 0.7V to address all low voltage power needs. The MIC22700 offers a full range of sequencing and tracking options. The Enable/Delay pin combined with the Power Good/POR pin allows multiple outputs to be sequenced in any way during turn-on and turn-off.
