A voltage regulator having a series regulator transistor with a potential threshold device for preventing saturation. The potential threshold device includes a voltage divider and diode connected between the input electrode and a control device connected to the control electrode of the series regulator transistor whereby a control voltage applied to the control electrode is decreased when the potential difference between the input and control electrodes decreases below a threshold level. A pincushion correction waveform is also applied to the control electrode to modulate the regulated voltage with a pincushion correction signal.
