SolderingIronDriver by Bogdan Kecman

@Gosha
Evo jedan primer i kako izgleda shematski ekvivalent za TL431, informativno, mozda bude od pomoci radi lakseg razumevanje rada, meni je pomoglo.
Unutra ima naponska referenca od 2.5V koja je vezana na +In od OP-a, -In je ustvari REF pin, izlaz iz OP-a je open-colector tipa (katoda).
Ceo taj interni sklop mora da ima bias struju od nekih 1mA da bi se to sve unutra napajalo, moze i manje ali se pri 1mA ili vise garantuje linearnost.
Odprilike sva pravila oko OP-ova vaze i za TL431, open-loop gain, GBWP, napon na +/-In ce pokusavati da se odrzi jednakim ("pokusavati", ne i da ce bezuslovno biti jednak) ...

Ovde je jedan koristan dokument sa primenom TL431 kao FB pojacavac kod naponskih regulatora i nacin frekvetne kompenzacije.
