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
