MIC5248 General Description

The MIC5248 is an efficient, precise CMOS voltage regulator with power good output. The MIC5248 offers better than 3% initial accuracy, and constant ground current (typically 100A) over load.

The MIC5248 also works with low-ESR ceramic capacitors,reducing the amount of board space necessary for power
applications, critical in handheld wireless devices.

Key features include current limit, thermal shutdown, a pushpull output for faster transient response, and an active clamp to speed up device turnoff. Available in the IttyBitty™ SOT-23-5 package, the MIC5248 is a fixed 1.2V regulator.
