take an LM317t an adjustable voltage regulator.. depending on the voltage divider on the reference pin determines the voltage out... how is that resistance produced digitally?

can PWM and Resistance be exchanged?

You want (precisely) an N-Channel Enhancement Mode MOSFET - they are 10 a penny from any electronics supplier.

Link, please. (:
