Hi All,
I'm totally new and only just started getting into the electronic stuff, I can't work out this circuit, i know it works but I cant see how! http://www.lm317-circuits.com/3-3v-5v-regulated-power-supply.html
To me it looks like the current will go from the source, through the diode, into the LM317 and straight out (to where it says 3.3v/5v) why would the current go through the resistor? I thought the current goes for the least resistance path it could?
Say i connected a LED from the 3.3v/5v label to ground I cant see why the current would go through the resistor to get to LM317's ADJ, or am I missing something fundamental?
Thanks!
