ADP199

Data Sheet 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 3.6 V, 500 mA Logic Controlled High-Side Load Switch ADP199 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. 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 curre...
