Back to basics ii.
This tutorial explains everything you need to know about the lm317 adjustable regulator like for example.
10 1 25x 1 r2 240 r2 1680ω.
It can supply greater than 1 5 a at the output.
Adjustable current regulator with the lm317 lm317 datasheet.
Working of lm317 voltage regulator circuit.
The adjustable pin is connected with the two external resistor and connected with the vout pin of the ic.
In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads.
