Abstract
A power source circuit according to an embodiment includes: first and second transistors connected to a current path between an input terminal and an output terminal; a first node that supplies a first control voltage to a gate of the first transistor; a comparator with a first input terminal to which a voltage supplied to the input terminal is applied and a second input terminal to which a voltage appearing at a second node being a connecting point of respective drains of the first and second transistors is applied, the comparator being configured to compare voltages of the first input terminal and the second input terminal to each other and to control the first control voltage to be supplied to the first node based on a comparison result; and a diode connected between the first input terminal and the second input terminal of the comparator.
