LM317, LM350, LM338 voltage regulator or current limiter calculator

This calculator is an online tool to quickly determine the resistor value required to use the LM317 / LM350 / LM338 as a voltage regulator circuit or current limiter circuit.

LM317, LM350, LM338 are adjustable three-terminal positive-voltage regulators. They require two external resistors to set the output voltage in voltage regulator circuit or one external resistor to set the output current limit.

For voltage regulator circuit enter the target output voltage (Vout) and the value of R1 resistor to calculate the value of R2 resistor.

For current limiter circuit enter the target output current to calculate the value of R1 resistor.
