Abstract
A regulator includes: 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 such that a voltage of the output terminal approaches a target voltage according to a feedback voltage proportional to the voltage of the output terminal; a second transistor having one end connected to the input terminal and a control electrode to which the control voltage is applied in common with the first transistor; and a clamp circuit configured to set the other end of the second transistor to a voltage determined by the voltage of the output terminal.
