1. In a stabilized voltage source of the type having a temperature-dependent actual voltage gauge which senses the output voltage of the voltage source, a reference value circuit providing a reference value voltage, said reference value circuit comprising a temperature-stable first voltage source and a second voltage source which is strongly dependent on temperature, means for summing the voltage outputs of said first and second voltage source of said reference value circuit, and means for regulating the output voltage of at least one of said first and second voltage sources to control the reference value voltage for regulating the temperature coefficient of the reference value voltage to compensate for temperature dependence of the actual value voltage.
