MIC5268
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
100
μ
A)over load .
The MIC5268 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 MIC5268 is a fixed 1.2V regulator.
