Default L1117 driver schematic

I'm sorry i know it somewhere on this forum but i can't seem to find it even with the search bar

So, could someone provide me the L1117 driver schematic or lead me to the proper thread?

Thank you

so just substitute the LM317T with a L1117 regulator.

Shouldn't there be a ghange in the resistors?

uhh yes..
and you use resistors to set the current... doesnt matter what regulator it is..
so if you want to use it for a phr diode
use 10+1 ohm resistors in series for 11ohm so you get about 114mA..
