ABSTRACT:
A voltage supply circuit includes an output transistor causing a first current to flow to an output terminal of the voltage supply circuit based on a control voltage applied from an error amplifier to a control terminal of the output transistor; and an overcurrent protection circuit including a reference transistor causing a second current to flow to the output terminal, the second current having an amount corresponding to an amount of the first current, the overcurrent protection circuit regulating a level of the control voltage based on comparison between a detection voltage caused based on the second current and a reference voltage.
