Abstract
A semiconductor circuit converts an applied input voltage into a desired output voltage and outputs the same from a voltage output terminal. A first resistor, a second resistor, and a third resistor are connected in series between the voltage output terminal and a ground terminal. When a switch is brought to an open state, an output voltage based on a voltage divided by a combined resistance of the second and third resistors and the first resistor is supplied. When the switch is brought to a closed state, an output voltage based on a voltage divided by the second and first resistors is supplied. The semiconductor circuit has a configuration of controlling the resistance value of each voltage division resistor by a control signal from the outside.
