Microchip MIC2951-03YM, 1 Low Dropout Voltage, Voltage Regulator 150mA, 5 V 8-Pin, SOIC

The MIC2950 and MIC2951 are "bulletproof" micropower voltage regulators with very low dropout voltage (typically 40mV at light loads and 250mV at 100mA) and very low quiescent currents. Like their predecessors, the LP2950 and LP2951, the quiescent current of the MIC2950/MIC2951 increases only slightly in dropout, thus prolonging battery life.
