ADP5301 Datasheet (Analog Devices) - Ultralow Power Step-Down Regulator

ADP5301, Ultralow Power Step-Down Regulator

The ADP5301 is a high efficiency, ultralow quiescent current step-down regulator that draws only a 180 nA quiescent current to regulate the output at no load.

The ADP5301 runs from an input startup voltage range of 2.15 V to 6.50 V, allowing the use of multiple alkaline/NiMH, Li-Ion cells, or other
