ADP5304 - Analog Devices

ADP5304 Ultralow Power Step-Down Regulator

The ADP5304 is a high efficient, ultralow quiescent current step-down regulator that draws only 260 nA of quiescent current to regulate the output at no load. The ADP5304 runs from an input voltage range of 2.15 V to 6.50 V, allowing the use of the multiple alkaline, NiMH, and Lithium cells, or the use of a high impedance power source. The output voltage is .
