AP2281
SINGLE SLEW RATE CONTROLLED LOAD SWITCH
Description
The AP2281 slew rate controlled load switch is a single P-channel
MOSFET power switch designed for high-side load-switching
applications. The MOSFET has a typical R
DS(ON)
of 80m  at 5V,
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 0.01µA.
