The Dimension Engineering DE-SWADJ is an adjustable down voltage regulator. It is designed to be the easiest possible way to add an adjustable voltage source to a new or existing project with all the efficiency benefits of a switch-mode power supply. The DE-SWADJ 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. It has integrated decoupling capacitors, so external capacitors are not generally necessary.

DE-SWADJ can deliver a maximum of 10 Watts.

The screw potentiometer on DE-SWADJ is worm-gear driven, so small vibrations and movement will not cause the voltage to shift.

Specifications:

• Adjustable from 1.25 to 13V output using screw
• 1A output at 1.25 to 10V
  (Please see datasheet for current ratings at higher voltages)
• >90% efficiency at >9v out
• 1.3V typical dropout voltage at full load
• Can be put in parallel
