LM317 Adjustable Regulator

Use a trimmer on the board for the adjustment pot (R2).  Omit the transformer and rectifier if you already have a DC power supply that is at least a couple of volts above your desired output voltage. 

This is pretty much straight from the LM317 data sheet (http://www.ti.com/lit/ds/slvs044u/slvs044u.pdf)
