The AP2280 slew rate control°C load switch is a single P-channel MOSFET power switch designed for high-side load-switching or power distribution applications. The MOSFET has a typical RDS(ON) of 80mΩ at 5V, allowing increased load current handling capability with a low forward voltage drop. The turn-on slew rate of the device is control°C internally to reduce turn-on inrush current. The AP2280 load switch is designed to operate from 1.5V to 6.0V, making it ideal for 1.8V, 2.5V, 3.3V, and 5V systems. The typical quiescent supply current is only 0.004uA, making it ideal for battery powered distribution system where the power consumption is a concern.
