Hi
I'm trying to make a 12V power supply that also provides 5v 3v and 1.5. Am not too sure how to limit it to 12V at 25ma of current.
Also I seen a resistor on the resistor between gnd and reference, is that because the output can be higher than the voltage used to power the regulator? IF so I wouldn't need one right because my voltage supply is 15 and the output is 12 right?
I'll be using an 15V unregulated power supply.
