Lm317 Adjustable Voltage Regulator Tutorial

In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads.

Lm317 adjustable voltage regulator tutorial.

The adjustable pin is connected with the two external resistor and connected with the vout pin of the ic. Back to basics ii. Lm317 voltage regulator comparison with 78xx series of regulators. Lm317 is a positive voltage regulator with an adjustable voltage range from 1 25 v to 37 v.

For example if the target output voltage is 10v then the r2 value is calculated as following. So this is how we calculate the r2 and output voltage for lm317 voltage regulator circuit. Eu 220v diy lm317 adjustable voltage power supply board learning kit with case assembling lm317 adjustable voltage power supply for your own you can get ad. It can supply greater than 1 5 a at the output.

Lm317 adjustable regulator in this tutorial you will learn how to make an adjustable variable voltage power supply based on the lm317 regulator. The capacitor c1 used for the filtering of dc input voltage and further fed to the vin pin of the lm317 voltage regulator ic. 10 1 25x 1 r2 240 r2 1680ω. Adjustable current regulator with the lm317 lm317 datasheet.

This voltage regulator circuit is very simple.
