MIC5258
General Description
The MIC5258 is an ef?cient, precise CMOS voltage regula-
tor with power good output. The MIC5258 offers better than
3% initial accuracy, and constant ground current (typically
100μA)over load .
The MIC5258 also works with low-ESR ceramic 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 MIC5258 is a ?xed 1.2V regulator.
