Buck Regulator - 5V/1.5A

Only 21 left


Highly efficient buck regulator that can easily regulate 5V from typical 12-24VAC sources (rectified through a 1N4007 diode).
This was the regulator of choice in the door bell project described here.
Datasheet: Murata OKI-78SR-5/1.5-W36-C

  • Input voltage range: 7-36V (tested to 38V, stable and does not warm up)
  • Output voltage : 5V
  • Output current: 1.5A
  • LM7805 drop in replacement without the heating problem of linear regulators
