1. A monolithically integratable voltage stabilizer comprising:

  • a first bipolar transistor of a first type of conductivity having an emitter terminal which is connected to ground via a capacitor, and having a collector terminal which forms an output terminal of the stabilizer, and having a base terminal;

    a differential amplifier having an output terminal which is connected to said base terminal of said first bipolar transistor and having a first input terminal which is connected to a voltage divider connected between said output terminal of the stabilizer and ground, and having a second input terminal which is connected to a first voltage reference;

    a second bipolar transistor of said first type of conductivity having an emitter terminal which forms an input terminal of the stabilizer, and having a collector terminal which is connected to said emitter terminal of said first transistor and having a base terminal which is connected to a biasing and switching circuit means disposed between said base terminal of said second transistor and ground and said input terminal of the stabilizer.
