1. A temperature-compensated voltage regulator, which comprises:

  • voltage buffer means having a high-voltage input, a control input and a low-voltage output;

    voltage generator means for generating a reference voltage and having a first terminal coupled to the low-voltage output of said voltage buffer means and a second terminal, said voltage generator means comprising a series connection of a zener diode and at least one p-n junction diode;

    current mirror means having an input coupled to said second terminal, an output coupled to the control input of said voltage buffer means, and a common terminal; and

    resistive means for coupling said current mirror output to the low-voltage output of said voltage buffer means, a temperature-compensated, regulated output voltage being generated during operation between said first terminal and said common terminal.
