GENERAL DESCRIPTION
The ADP198 is a high-side load switch designed for operation between 1.65 V and 6.5 V that is protected against reverse current flow from output to input. A load switch provides power domain isolation, thereby helping to keep subsystems isolated and powered independently and enabling reduced power consumption.

FEATURES
    Low RDSON of 50 mΩ @ 3.3 V (WLCSP only)
    Low input voltage range: 1.65 V to 6.5 V
    1 A continuous operating current
    Built-in level shift for control logic that can be operated by 1.2 V logic
    Low 2.5 μA quiescent current @ VIN = 2.8 V
    Low 1.1 μA shutdown current @ VIN = 2.8 V
    Reverse current blocking
    Programmable start-up time
    Ultrasmall 1 mm × 1 mm, 4-ball, 0.5 mm pitch (WLCSP)
    Tiny 8-lead lead frame chip scale package (LFCSP) 2.0 mm × 2.0 mm × 0.55 mm, 0.5 mm pitch

APPLICATIONS
    Mobile phones
    Digital cameras and audio devices
    Portable and battery-powered equipment
