in primul rand ca 7808 cum am mai spus nu e tranzistor , in al doilea rand sune ce fel de sursa reglabila sau fixa? ce tensiuni iti trebuie ce curent? pt un incepator ar fi buna una cu lm317 nnumai ca aceasta debiteaza un curent relativ mic dar e numai buna pt alimentat montaje cu leduri.

uite o schema functionala http://www.electronics-lab.com/projects/power/010/

pt 7808 gasesti schema in datasheet figura3 http://sigma.octopart.com/5578/datashee ... 7808CV.pdf
