ABSTRACT:
A STIFF POSITIVE FEEDBACK TO THE VOLTAGE REGULATOR TAP AT WHICH THE Zener diode in circuit with the control transistor of the regulator is called into play accelerates the switching operation at the operating thresholds of the regulator, while a negative feedback from the same regulator terminal, with inversion produced by a transistor, is applied to a second tap of the voltage divider farther from ground, where its effect is delayed by a capacitor that also serves to filter the command voltage applied to the regulator. The transistor that inverts the feedback acts as a controlled current source drawing current from the second voltage tap. The circuit is highly compatible with production by integrated circuit technology.
