PSU3-5 40V to 5V 1A High Efficiency Regulator

This is a 5V 1A switch-mode voltage regulator. It is a high-efficiency replacement for popular three-terminal linear regulators. It is pin-to-pin compatible with the common LM7805 linear regulators. The maximum output is 1A of continuous current. It is a true drop in replacement for a TO-220 LM7805. All the required capacitors are included on the module, no external capacitors are required. No heatsink required, even at 1A continuous. The output voltage guaranteed to be within +/-2% tolerance. The module has thermal shutdown and current limit protection. Definitely no heatsink required. The board is small in size and breadboard friendly, making it an ideal solutions for breadboard prototyping.

• Drop-in replacement of 3-terminal LM7812 or equivalent linear voltage regulator.
