NJM2388 (daca e TO220-4). Este un regulator de tensiune (8.4V) cu comanda on/off.84 de pe al doilea rand insemna tensiunea de iesire, in acest caz 8,4V

Multumesc, acum marea intrebare este de unde pot cumpara acest regulator (nu ma trimiteti pe e-bay sau alte coclauri) sau vreun echivalent ceva care sa-l pot lua de pe la noi din tara ?
