General Description

The MIC5268 is an efficient, precise CMOS voltage

regulator with power good output. The MIC5268 offers

better than 3% initial accuracy, and constant ground

current (typically 100µA) over load.

The

capacitors, reducing the amount of board space necessary

for power applications, critical in hand-held wireless

devices.

Key features include current limit, thermal shutdown, a

push-pull output for faster transient response, and an

active clamp to speed up device turnoff. Available in the

IttyBitty™ SOT-23-5 package, the MIC5268 is a fixed 1.2V

regulator.
