i made an LM317 driver.
it uses an lm317 200 ohm pot between the two left pins a capacitor.
when setting the current i can easily get it to 120 then it will make a big jump to 180 (if im lucky and it doesnt go straight over 200) then it goes of the scale on my DMM (goes up to 200mA then 10A )
anyone know why it jumps like this?
cheers
[EDIT] this hapens while adjusting the pot not just randomly
