Dimension Engineering 25W Step Down Adjustable Switching Regulator The Dimension Engineering DE-SWADJ 3 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.
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.
Performance: Adjustable from 3 to 13V output using screw
3A output at 3 to 8V
(Please see datasheet for current ratings at higher voltages)
1.2V typical dropout voltage, 2.0v maximum at full load
Applications: Battery powered applications
Powering multiple servos at their max rated voltage
