DC-DC 5V LDO Linear Regulator Module APM Flight Controller with Built-in Compass A Straw Hat LED featuresThe 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 such as the LM7805. 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.
