Abstract
A voltage regulator which suppresses an inrush current at the time of power application has input and output terminals, a power supply connected to the input terminal, a switch circuit connected to the power supply, a coil connected between the switch circuit and the output terminal, a rectifying device connected in series between the coil and the output terminal, an output capacitor connected to the output terminal, a switching element connected between the coil and the rectifying device, a driving circuit for driving the switching element, a transistor connected between the power supply and the coil, and a control circuit connected to the transistor for gradually varying an ON resistance of the transistor from a relatively large value immediately after the switch circuit is turned on to a relatively small value a predetermined time thereafter to limit a rush current flowing into the output capacitor from the power supply.
