Device Overview

Summary

The MCP1703A is a CMOS, low dropout voltage regulator with 250 mA maximum output current. MCP1703A works with input voltages up to 16V and with its low 2 µA current consumption it is an ideal solution for applications using multi-cell, 9V alkaline or one-, two- or three- cell lithium-ion batteries. It is available in space efficient SOT23A and SOT89 packages; or in a thermally capable 3-pin SOT223 and 8-pin 2x3 DFN.
