Abstract
Provided is a voltage regulator which is not affected by a variation in output impedance of a reference voltage circuit, that is, which is configured to output voltage with a small change due to temperature. Two reference voltages respectively having positive and negative temperature coefficients are added together through transconductance amplifiers having large input impedances, respectively, and the resultant is amplified.
