LM317 Calculator is used to calculate voltage regulation and Constant Current Regulation. There are several LM317 Calculator available on the web but very few of them are actually user friendly. This LM317 calculator is really simple and user friendly. You can calculate Output Voltage, Output Current Limit and the values of two voltage divider resistances using this online tool.
R1 = 240 ohm
R2 = 10k ohm
Vout = 6.458333333333334 Volts
I think its incorrect.
Vout=1.25(1 + R1/R2) + Iadj * R2 where we can omit Iadj * R2 porrtion as Iadj is very low in amount.
Using this formula we get 1.28 volt.
R1 = 240 ohm
R2 = 33 ohm
Vout = 1.265625 Volts
Using this formula, this time we get 10.34 volt.
Please correct me if I’m wrong.
