  • Adjustable step-down switching DC-DC converter
  • Output voltage adjusted via a small potentiometer (3 to 13V), 3A
  • Integrated decoupling capacitors

The Dimension Engineering 25W Adjustable Switching Regulator is a larger version of our DE-SWADJ adjustable step down voltage regulator. Previously it was necessary to put multiple DE-SWADJ units in parallel to achieve ratings over 1A, which was bulky, expensive and carried with it a considerable increase in dropout voltage. The DE-SWADJ 3 is designed to be stronger, faster and better. It can process 3A of current, typical ripple is 25mV and under ideal circumstances the regulator can be up to 96% efficient.

25W Adjustable Switching Regulator

It continues the ease-of-use of the DE-SWADJ, making it simple to add an adjustable voltage source to a new or existing project with all the efficiency benefits of switch-mode power. The DE-SWADJ 3 is pin-compatible with the common 78XX family of linear voltage regulators, and has a small screw on top that allows you change the output voltage as your project evolves. It has integrated decoupling capacitors, so external capacitors are not generally necessary.

DE-SWADJ3 can deliver a maximum of 25 Watts.

The screw potentiometer on DE-SWADJ is worm-gear driven, so small vibrations and movement will not cause the voltage to shift. Use of glue to hold the screw in place is strongly discouraged and could damage the device.

excellent voltage regulator

This voltage regulator is a little pricey but the applications for this is endless. Make sure you have a multimeter to measure the output voltage when adjusting the regulator.

Excellent Product!

I use these as a drop in replacement for my LM regulators and they do an excellent job! I also have battery longevity in mind and these fit the build. I've purchased several of these over the last few years and no failures.
