Abstract
Abstract A parallel voltage regulator having an improved factor of stabilization since a reference voltage from a Zener diode is used, this Zener diode being supplied, via a resistor, with a stabilized auxiliary voltage. The stabilized auxiliary voltage is obtained as the sum of an output voltage and of a voltage drop in a semi-conducting diode polarized in a specific direction.
