(Not Recommended for new design)

The SOT223-5 Voltage Regulator Evaluation Board is designed to be used to facilitate the evaluation of Microchip’s voltage regulators or to be used as a standalone voltage regulator board. Jumpers have been placed on the board to facilitate testing of specific voltage regulator parameters. The jumpers may also be used to select pull-up and pull-down voltage levels.
