Hello friends, today’s tutorial is a bit different in its genre. Its not some kind of engineering tutorial for engineers, instead its a tool for engineer 🙂 I am quite excited while posting it as I was trying for a long time to post it but couldn’t done it because of few problems. Anyways, its here now and is ready to be utilized. Its nothing but a simple LM317 Voltage Calculator. It calculates the Vout of IC regulator LM317 when the voltage values of both the resistances R1 and R2 is given to it.

Its simple and easy to use, simply give the values of R1 and R2 and hit the Calculate button and it will calculate the output voltage. LM317 is an IC regulator which is used to regulate the output voltage and its output voltage is regulated depending on the values of both the resistances attached at its output. Here’s our first simple but awesome tool. 🙂

  •  The simple formula used for calculating the output voltage of LM317 is shown below:

  • Normally it is not required to use very specific output voltage and normally a predefined combination of resistors is used. Here’s a list of normally available resistors, the output voltages for these resistor combination is shown in below table:
