The AP2281 slew rate controlled load switch is a single P-channel

MOSFET power switch designed for high-side load-switching

allowing increased load current handling capacity with a low

forward voltage drop. The turn-on slew rate of the device is

controlled internally.

The AP2281 load switch is designed to operate from 1.5V to 6V,

making it ideal for 1.8V, 2.5V, 3.3V, and 5V systems. The typical

quiescent supply current is only 0.01uA.
