    摘要: A constant voltage circuit includes an output control transistor to control an output current from an output terminal to keep an output voltage constant at a set voltage; and an excess-current protection circuit to control the output control transistor. The excess-current protection circuit includes a current increase restriction element to restrict increase in the output current to decrease the output voltage; a first current limitation circuit to limit a gate voltage of the output control transistor to decrease the output current, when the output voltage is decreased to a first limited voltage; a second current limitation circuit to limit a gate voltage of the output control transistor to decrease the output current, when the output voltage is decreased to a second limited voltage smaller than the first limited voltage; and a selector to select whether the first current limitation circuit is operated or stopped.
