Microchip Technology MIC5239-5.0YMM

MIC5239-5.0YMM Description
The MIC5239-5.0YMM is a low quiescent current, µCap low-dropout regulator. With a maximum operating input the voltage of 30V and a quiescent current of 23 µA, it is ideal for supplying keep-alive power in systems with high-voltage batteries. Capable of 500 mA output, the MIC5239 has a dropout voltage of only 350 mV. It can provide high output current for applications such as USB. As a µCap LDO, the MIC5239 is stable with either a ceramic or a tantalum output capacitor. It only requires a 3.3 µF output capacitor for stability.
