Abstract
Improvements in the voltage stabilizers, for the generation of low voltages, carried out according to the technology of integrated circuits, of the type in which a transistor (T19), which acts as an element of variable resistance, is inserted in series in one of the supply wires and a regulation ring make the comparison between the stabilizer output voltage and a reference voltage, controlling with a regulation signal the conduction level of the transistor (T19), characterized in that the reference voltage is made up of the input voltage of an amplifier stage comprising a final transistor (T16) with the emitter to ground, preceded by a number of voltage step transistors in cascade, each connected with the emitter to the base of the next, which ensure the desired input voltage and that the output voltage (V0) of the stabilizer is brought to the input of said amplifier by means of a drop resistance (R9), traveled by the input current to the amplifier and by a current (Ic13) regulated by a circuit for compensating the thermal coefficient of the reference voltage.
