LM317 CV V 2

LM317 Output Voltage Calculator

Enter any two values among R1, R2, and Output Voltage (Vout). Leave the third one blank to calculate it.

Resistor R1:

Resistor R2:

Output Voltage (V):

Note: The LM317 output voltage is calculated using: Vout = 1.25 × (1 + R2 / R1). Ignores I_adj for simplicity.
