GENERAL DESCRIPTION
The ADP195 is a high-side load switch designed for operation
between 1.1 V to 3.6 V and protected against reverse current
flow from output to input. This load switch provides power
domain isolation helping extended power domain isolation. The
device contains a low on-resistance, P-channel MOSFET that
supports over 1.1 A of continuous current and minimizes power
loss. The low 1 μA of quiescent current and ultralow shutdown
current make the ADP195 ideal for battery-operated portable
equipment. The built-in level shifter for enable logic makes the
ADP195 compatible with many processors and GPIO
controllers.

2.0 mm × 2.0 mm × 0.55 mm, 0.65 mm pitch
APPLICATIONS
Mobile phones
Digital cameras and audio devices
GPS devices
Personal media players
Portable and battery-powered equipment
In addition to operating performance, the ADP195 occupies
minimal printed circuit board (PCB) space with an area of less
than 1.0 mm2 and a height of 0.60 mm.
It is available in an ultrasmall 1 mm × 1 mm, 4-ball, 0.5 mm
pitch WLCSP. A 6-lead 2 mm × 2 mm × 0.55 mm, 0.65 mm
pitch LFCSP is also available.
