Abstract
There is provided a regulator including: a first transistor connected between an input terminal and an output terminal; a feedback circuit configured to control a control voltage of a control electrode of the first transistor so that a voltage of the output terminal reaches a target voltage according to a feedback voltage proportional to an output voltage; a second transistor having a control electrode to which the control voltage is applied in common with the first transistor; a first resistor connected with the second transistor in series between the input terminal and the output terminal; and a current limiting circuit configured to detect a voltage generated across the first resistor and to change the control voltage so as to limit a current flowing through the first transistor.
