Patent ID: 7663353

Claim:
A circuit arrangement for voltage regulation, comprising: an output, at which a voltage-regulated output potential can be tapped off; a controllable output transistor connected to said output on a load side; said output transistor comprising a control terminal; an error detection circuit providing a regulating signal if a deviation between said output potential or a potential derived from said output potential and a desired value occurs; by means of said regulating signal said control terminal can be charged or discharged dependent on said deviation, a monitoring control circuit monitoring said regulating signal and performing, if said regulating signal lies outside a predetermined range, an additional charging or discharging of said control terminal until said regulating signal lies within said predetermined range, and an operating point adjusting circuit for adjusting an operating point of the output transistor, the operating point adjusting circuit coupled between the monitoring control circuit and the control terminal of the output transistor and having a controllable charging circuit for generating a charging current for charging said control terminal and a discharging circuit for discharging said control terminal by means of a discharging current.
