Microchip | MIC5236YM

The MIC5236YM is a low quiescent current, µCap low-dropout regulator. With a maximum operating input voltage of 30 V and a quiescent current of 20 µA, it is ideal for supplying keep-alive power in systems with high-voltage batteries.

Capable of 150 mA output, the MIC5236 has a dropout voltage of only 300 mV. It can also survive an input transient of –20 V to +60 V. As a µCap LDO, the MIC5236 is stable with either a ceramic or a tantalum output capacitor. It only requires a 1.0 µF output capacitor for stability.

The MIC5236 includes a logic compatible enable input and an under voltage error flag indicator. Other features of the MIC5236 include thermal shutdown, current-limit, over voltage shutdown, load-dump protection, reverse leakage protections, and reverse battery protection. Available in the thermally enhanced SOP-8 and MSOP-8,
