Description

General part information

MCP1722 Series

MCP1722 is a dual output, high voltage, low dropout (LDO) regulator, designed to supply a μProcessor with either 3.3V or 5.0V. It has a current capability of 100mA, while also providing 10V or 12V to a motor driver with a current capability of 50 mA. These specifications make it ideal for handheld power tools with 20V battery packs.

MCP1722 comes with Power Good indicators (two pins, PWG1 and PWG2) for both outputs and shutdown functionality (a single SHDN pin) that places the part in a low current consumption state, of only 4 μA.

The device comes in two 8-lead DFN or SOIC packages, both with exposed pads, for improved thermal dissipation. While in operation, MCP1722 is fully protected by thermal shutdown protection and current foldback limiting.
