Final Information
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 100µA)
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 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 MIC5248 is a fixed 1.2V regulator.
