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 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
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.
Data sheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
