The ADP199 is a high-side load switch designed for opera-TIon between 0.9 V to 3.6 V. A load switch provides power domain isolaTIon， thereby helping to keep subsystems isolated and powered independently， and enabling reduced power consumpTIon.
The ADP199 contains a low on-resistance， N-channel MOSFET to minimize power loss， and supports over 500 mA of conTInuous load current. The low 6 µA quiescent current and ultralow shutdown current make the ADP199 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP199 compatible with many processors and GPIO controllers.
In addition to high performance， the ADP199 occupies mini-mal printed circuit board （PCB） space with an area of less than 0.64 mm2 and a height of 0.50 mm.
The ADP199 is available in an ultra-small， 0.8 mm × 0.8 mm × 0.5 mm， 4-ball， 0.4 mm pitch WLCSP.
