MCP1703

For product comparison, please consider:

The MCP1703 is a CMOS, low dropout voltage regulator with 250 mA maximum output current. MCP1703 works with input voltage of up to 16V and in combination with its low current consumption of 2 µA 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.

For new designs, please consider the MCP1703A, which contains several improvements over the MCP1703.

Features
