Ovako, LM317T u spoju ogranièavaèa struje, ulazni napon 9V, izlazni 3V, struja 375mA i grije se ko lud.

Otpornik za ogranièenje struje je 3.3 Ohm, sve radi super ali mi nije jasno za¹to se LM317T tako jako grije?????

Snaga na regulatoru (9-3)*0.375=2W ,odprilike. Zasto se cudis sto se grije. Stavi neki hladnjak na regulator i stvar je rjesena.
