Abstract
A linear regulator includes an input terminal configured to receive an input voltage, an output terminal configured to be applied with an output voltage, an output transistor connected between the input terminal and the output terminal, and constituted by a P-channel MOSFET, a gate control circuit configured to control a gate voltage of the output transistor to stabilize the output voltage at a target voltage based on a feedback voltage corresponding to the output voltage, and an additional circuit, wherein a control range of the gate voltage controlled by the gate control circuit is equal to or higher than a predetermined lower limit voltage, and wherein the additional circuit is configured to lower the gate voltage to below the lower limit voltage when the output voltage falls below a determination voltage lower than the target voltage.
