Description
The AP2280 slew rate controlled 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
R
DS(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 controlled 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.
