LFCSP 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. The ADP198 contains a low on-resistance P-channel MOSFET that supports more than 1 A of continuous load current. The low 2.5 μA quiescent current and ultralow shutdown cur...
