Microchip | MIC5256-2.5YM5-TR

The MIC5256-2.5YM5 TR is an efficient, precise CMOS voltage regulator. It offers better than 1% initial accuracy, extremely low-dropout voltage (typically 135 mV at 150 mA) and low ground current (typically 90 µA) over load. The MIC5256 features an error flag that indicates an output fault condition such as over current, thermal shutdown and dropout.

The MIC5256-2.5YM5 TR also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. 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 1 mm tall.
