An adjustable voltage regulator generates a DC output voltage that can be finely tuned within a specific voltage range. This type of regulator is commonly referred to as a variable voltage regulator. The DC output voltage from an adjustable voltage regulator can be either positive or negative.

-
Solder a wire to the right terminal of the LM317 as the positive input.
-
Solder the positive output wire to the middle terminal of the LM317.
-
Connect the resistor from the middle terminal of the LM317 to the left terminal of the LM317 by soldering.
-
Connect the right terminal of the potentiometer to the left terminal of the LM317.
-
Attach a negative input to the middle terminal of the potentiometer.
-
