am si eu o intrebare:se poate folosi acest stabilizator alimentat direct de la 24v(auto) pt obtinerea tensiunii de 12v pt alimentarea unui cd-player ,sau mai trebuie redusa tensiunea inainte? daca da atunci va rog sa ma ajutati cu o schema daca se poate

Daca e pana in 4A puteti folosi o sursa stabilizata in comutatie de la 24 la 12V.

O varianta ar fi L4964, cu protectie la scurtcircuit.

Avantajul este ca disipa mult mai putin decat un stabilizator clasic liniar cu 7805.

Eu nu l-as folosi sincer.Dar nici nu ai raspuns cat consuma CDul ala.Eventual comanda cu un LM317(configurat pe 12V) un tranzistor sau doua in paralel si asa merge.Sau cum spune colegul sursa in comutatie.
