DD4012SA DC/DC Switching Regulator (LM78xx TO220 Replacement)


This product is currently out of stock and unavailable.

SKU: N/A Categories: ,


These switching regulators are a drop-in replacement for the inefficient LM7805/LM7803 linear regulators.  In fact, they are slightly easier to use since they have bypass capacitors onboard and don’t require them in the circuit. (but they won’t hurt if they’re already there)

Input: 4.75-40v (3.3V version) or 6.6-40V (5V version)
Output: 3.3V and 5.0V models available
Max output current: 1A
Switching frequency: 550khz
Efficiency: 75-90%
