ABSTRACT:
A circuit arrangement for voltage regulation comprises an output, a controllable output transistor connected to the output, an error detection circuit, and a monitoring control circuit. A voltage-regulated output potential can be tapped off the output, the controllable output transistor is connected to the output on a load side and the output transistor comprises a control terminal. The error detection circuit provides a regulating signal if a deviation between the output potential or a potential derived from the output potential and a desired value occurs. By means of the regulating signal the control terminal can be charged or discharged dependent on the deviation and the monitoring control circuit monitors the regulating signal and performs, if the regulating signal lies outside a predetermined range, an additional charging or discharging of the control terminal until the regulating signal lies within the predetermined range.
