Vezi ca acela nu-i tranzistor, e integrat fiindca stabilizeaza tensiunea de iesire.Cu un simplu tranzistor nu s-ar obtine stabilitatea tensiunii.Acest tip de integrate se mai gaseste si prin unele lanterne cu invertor de la 1,2V.Am luat si eu acel montaj, dar nu poti obtine la iesire mai mult de 100mA, am incercat pe o baterie de telefon, oricum e folositor fiind mic si foarte compact.
