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 100µA) over load.
The
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.

... Micrel, Inc. Application Information Enable/Shutdown The MIC5248 comes with an active-high enable pin that allows the regulator to be disabled. Forcing the enable pin low disables the regulator and sends it into a “zero” off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output voltage. This part is CMOS and the enable pin cannot be left floating ...
