The ASR-10 is the adjustable version of our step down voltage regulators. 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 switch-mode power. The ASR-10 is pin-compatible with the common 78XX family of linear voltage regulators, and has a small screw on top that allows you to change the output voltage as your project evolves. It has integrated decoupling capacitors, so external capacitors are not generally necessary.
ASR-10 can deliver a maximum of 10 Watts.
The screw potentiometer on ASR-10 is worm-gear driven, so small vibrations and movements will not cause the voltage to shift. Use of glue to hold the screw in place is strongly discouraged and could damage the device.
