... 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 MIC5248 also works capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices ...

... 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 ...
