This is an adjustable voltage regulator for a Coherent Visible Laser Module. I've put a 1.2 k resistor across a 10 turn pot and this, together with my resistor choices should provide a maximum voltage of just over 5.2 volts.

If I had a smaller resistance 10 turn pot, I'd have been able to eliminate R3 and had a nearly linear output voltage; as it is, it looks like it will be a good driver circuit.

I'll edit this once I build and test the actual circuit.
