The AP2281 slew rate control°C load switch is a single P-channel MOSFET power switch designed for high-side load-switching applications. The MOSFET has a typical RDS(ON) of 80mΩ at 5V, allowing increased load current handling capacity with a low forward voltage drop. The turn-on slew rate of the device is control°C 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.
