ADP199
GENERAL DESCRIPTION
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.
