    • A reference voltage generating circuit that accurately corrects temperature characteristics of a BGR (bandgap reference) circuit and a regulator. A voltage dividing circuit outputs first and second voltages obtained by dividing a BGR voltage. The regulator includes a differential amplifier, first and second resisters coupled in series between the output terminal of the differential amplifier and the ground. The positive input terminal of the differential amplifier receives the BGR voltage, and the negative input terminal is coupled to a coupled node between third and fourth resistors. The BGR circuit outputs a third voltage varying with a temperature determined by a predetermined amount of current flowing in the BGR circuit and a predetermined resistor. A temperature-characteristics correcting circuit controls a correcting current flowing through the coupled node so that its magnitude varies with the difference between the first and third voltages, and the difference between the second and third voltages.
