A voltage generating circuit has: an operational amplifier, first to third voltage generating units, a first resistor and a second resistor. The operational amplifier generates a control signal depending on first and second voltages that are input thereto. The first voltage generating unit generates the first voltage depending on the control signal and outputs the first voltage from a first node. The second voltage generating unit generates the second voltage depending on the control signal and outputs the second voltage from a second node. The third voltage generating unit generates a third voltage as a reference voltage depending on the control signal and outputs the third voltage from a reference voltage output node. The first resistor is connected between the first node and the reference voltage output node. The second resistor connected between the second node and the reference voltage output node.
