GENERAL DESCRIPTION

The ADP199 is a high-side load switch designed for operation 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.

FEATURES

Constant low RDSON of 40 mΩ over input voltage range

Low input voltage range: 0.9 V to 3.6 V

500 mA continuous operating current at 85°C

1.2 V logic compatible enable input

Low 6 µA quiescent current, independent of load current

Ultralow shutdown current: <100 nA

Ultrasmall 0.8 mm × 0.8 mm × 0.5 mm, 4-ball, 0.4 mm pitch WLCSP

APPLICATIONS

Low operating voltage processors

Mobile phones

Digital cameras and audio devices

Portable and battery-powered equipment

Optical XMT/RCVR modules
