![]() ![]() ![]() The circuit is a just a modification of the ordinary voltage regulator using LM317. LM317 voltage regulator with digitally selected outputĪ very simple adjustable regulator circuit with digitally selected output is shown above. Adjustable regulator with digitally selected output. The output voltage of the regulator circuit depends on the equation, Vout = 1.25V (1 + (R2/R1)) + I adj R2. C1 is the input filter capacitor while C2 is the output filter capacitor. Resistor network comprising of R1 and R2 connected in association to the pin1 (adj) is used to set the output voltage. Input voltage is fed to the pin3 (v in) of the IC and regulated output voltage is available from pin 2 ( V out) of the IC. A classic voltage regulator circuit using LM317 is shown above.
