1. In a voltage regulator for providing a regulated output voltage at an output terminal, a temperature compensation network means coupled to a voltage supply for varying the output voltage with temperature as the voltage supply operates over a predetermined range of temperature, the temperature compensation network means comprising:

  • first means, coupled to the voltage supply, for producing a first signal which varies linearly over the predetermined range of temperature;

    second means, coupled to the voltage supply, for producing a second signal which varies nonlinearly over the predetermined range of temperature; and

    means for combining the first signal and second signal to provide the regulated output voltage at the output terminal.
