yes, a resistor will do just fine.philpoole said:I use a resistance to limit the current before the TL431. I think I use about 100R. Seems to work okay.
Is that what you mean?
Actually it appears, really quite good: and if you cascode two, they perform superbly well. See for yourself in Walt Jung's two 'Sources 101' papers on current-sources here:Is the 317 a good current source?
