Abstract
Viene descritto un regolatore (20) di tensione a bassa caduta, comprendente un transistore di potenza (6) di tipo P presentante un morsetto di ingresso (2) collegabile ad una sorgente di alimentazione (3), un morsetto di uscita (4) collegabile ad un carico (5) ed un morsetto di controllo pilotato dall'uscita di un amplificatore operazionale (21) il cui ingresso non invertente (+) è collegato ad un generatore (13) di tensione di riferimento e il cui ingresso invertente (-) è collegato al morsetto di uscita (4) del transistore di potenza (6). Per migliorare le caratteristiche di regolazione del regolatore (20) senza pregiudicarne la stabilità, anche in condizioni normalmente critiche, è prevista una rete di retroazione (24) includente un componente capacitivo (26) fra' l'uscita e l'ingresso invertente (-) dell'amplificatore operazionale (21).
