the problem was a bad connection... this is the first time i'm soldering:whistle: but as what you have said, i can't get more then 123mA out of it, need to buy an normal LM317. but is there a way to fix the broken pin of my diode?

i tried an another driver on the test load and got a reading from 200mV, so i think the test load is working.

so i can't get more then 100mA from this driver with this regulator? I wanted to get 380mA from this driver, so i think it's better to just buy another lm317? I was using 4 1n4001 diodes and an 1W 1Ohm resistor as test load. i tried it with 2 diodes and 1 ohm resistor and set the pot to 24ohm...

it doesn't matter, I still got the same results: 5,85V and no mv over the resistor:huh:

i have only connected 1 of the outputs, i'll try it with connecting all four of them.

here is the data sheet from the lm317, i have the square one with 8 pins

hello, I'm new here and need some help with my first driver. I build the lm317 driver and test load from rog's website. everything was going fine untill i got to the test section. i hooked up my first driver to the test load and connected it with 2 cr123a battery's wich gave me a total of 6,43V...
