Maybe that's contributing to the problem, specially if the leads between the pot and the regulator are inadequately decoupled to ground??
The setups I designed had about half an inch of PCB track between the IC and the pot; that's about the same as the ubiquitous Vellemann kits thta use the LM317. |
Not a clue pal, All i can tell you is it's working fine now after swapping the 5k pot for a 10k
