DC-DC 3.3V LDO Linear Regulator Module 0.1W It has output transition safeThe DC DC LDO is a TO 220 form factor DC DC Module. This is pin to pin compatible and is intended to replace existing linear regulators. The main benefit of using this DC DC is that it reduces the heat generated in the Linear Regulator (LDO) and reduces the design size because it eliminates the need for a separate heatsink on your board.
