Abstract
A power source device includes an output transistor connected between an input node at which an input voltage can be received and an output node at which an output voltage corresponding to the input voltage can be output according to a control voltage applied to a gate of the output transistor, a first amplifier that includes a first transistor element and a second transistor element having gates to which a first voltage is applied, receives a feedback voltage corresponding to the output voltage, and outputs a second voltage corresponding to a voltage difference between the feedback voltage and a reference voltage, a monitor transistor having a gate to which the first voltage is applied, a first current source that supplies a first current to the first amplifier, and a second current source that supplies a second current to the first amplifier according to a current flowing in the monitor transistor.
