Hello.I am built this shunt PSU but i shortcircuited the output and TL431 failed.I think the failure has to do with the AC unity gain capacitor C1=220uF.
Is a 220uF a normal value or shoud i use something lower around 22uF?
Does this capacitor discharges through reference pin of TL431 in case of an output shortcircuit and destroying TL431 ?
If yes ,how can i protect TL431 from being destroyed?
