Abstract (en)

The linear regulator is of the type having an MOS power transistor (1) of a first conductivity type (P), a first resistance (Rg) and a first control MOS transistor (16) of a second conductivity type (N). The regulator has a starting circuit (20) in series between the source and the grid of the MOS power transistor are a switched resistance (22) and see Fig.3, the first (MR) and the second (ML) MOS control transistors of the first conductivity type (P).

Abstract (fr)

L'invention concerne un régulateur linéaire du type comprenant un transistor MOS de puissance (1) d'un premier type de canal, commandé par un amplificateur (5) dont un étage de sortie comprend, entre deux bornes (3, 4) d'application d'une tension d'alimentation (Vbat), une résistance (Rg) et un premier transistor MOS de commande (16) d'un deuxième type de canal (N). Le régulateur comprend en outre un circuit de démarrage (20) comprenant une résistance commutable (22) en parallèle sur ladite première résistance. <IMAGE>
