MIC5256

MIC5256 Micrel MIC5256 150mA µCap LDO with Error Flag Final Information General Description The MIC5256 is an efficient, precise CMOS voltage regulator. It offers better than 1% initial accuracy, extremely lowdropout voltage (typically 135mV at 150mA) and low ground current (typically 90µA) over load. The MIC5256 features an error flag that indicates an output fault condition such as overcurrent, thermal shutdown and dropout. Designed specifically for handheld and battery-powered devices, the MIC5256 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero. The MIC5256 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, faster transient response, and an active clamp to speed up device turnoff. Available in the IttyBitty™ SOT-23-5 package and the new Thin SOT-23-5, which offers the same footprint as the standard IttyBitty™ SOT-23-5, but only 1mm tall. The MIC5256 offers a range of output voltages.
