Pai ai cerut Vca in primul post tocmai de aceea am pus schema aia. Pentru Vcc lucrurile se simplifica ( dar se si complica oarecum ), optiunile sunt mult mai multe, dar cel mai simplu este folosirea de regulator fix de 12V LM7812 ( asta in cazul in care curentul cerut nu depaseste 1A )

In cazul in care sursa care alimenteaza stabilizatorul este bine filtrata poti renunta la condensatorii din schema.
