Lm317 calculator

Below is our automated voltage calculator for the LM3and LM3regulators. In our article Using the LM3with LED Lighting we looked at how the LM317T (and high current equivalent LM338T) can be used to supply a fixed current to a . With this, you can calculate the value of resistor, R or the output voltage of the regulator.

This calculator is used to find the value of the voltage adjustment resistor required to set the output of an LM3to a specified level. You can use this Current Regulator Calculator to vary the value of the program resistor (R1) and calculate the output current from the LM317 . Enter the required output voltage and value of the Rresistor to calculate the Rresistor. Then use the nearest available value (listed at the bottom of the page) .
