LDO Regulator Pos 3.1V 0.5A 5Pin SOT-23
General Description
The MIC5219 is an efficient linear voltage regulator with high peak output current capability, very-low-dropout voltage, and better than 1% output voltage accuracy. Dropout is typically 10mV at light loads and less than 500mV at full load.
