General Description

The MIC5248 is an efficient, general purpose 1.2V CMOS

voltage regulator with a power good output function. The

MIC5248 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 handheld 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 and the tiny 6-pin 2mm x 2mm MLF

package.
