25W Step down adjustable switching regulator

Price: $25.00
Availibility: In Stock
Item #: P-VR-DE-SWADJ3


The DE-SWADJ 3 is an adjustable step down voltage regulator. 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. 

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-SWADJ3 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.
