Voltage Regulator adjustable/set 3v

Switching Voltage Regulator for regulating 12volts down.  Can be set to any lower voltage from 12 volts to 1 volt by turning the adjustment screw counter-clockwise.  If you need a specific voltage pre-set, just add your information in the message area at checkout.  Most common setting is for 3-volts so LEDs can be run without the limit resistor. I have preset these to 3-volt output but you can ask it to be changed.  Unless requested for a specific output; This regulator has been preset to 3 volts.
