The ADP194 is a high-side load switch designed for operaTIon from 1.1 V to 3.6 V and is protected against reverse current flow from output to input. This load switch provides power domain isolaTIon for extended power battery life. The device contains a low on-resistance P-channel MOSFET that supports more than 500 mA of conTInuous load current and minimizes power loss. The low 2 μA （maximum） ground current and ultralow shut-down current make the ADP194 ideal for battery-operatedportable equipment. The built-in level shifter in the enable logic input makes the ADP194 compaTIble with modern processors and GPIO controllers.
Beyond operating performance， the ADP194 occupies minimal printed circuit board （PCB） space with an area of less than
0.64 mm2 and a height of 0.50 mm. The ADP194 is available in an ultrasmall 0.8 mm × 0.8 mm， 4-ball， 0.4 mm pitch WLCSP.
