Patent ID: 6989660

Claim:
A circuit arrangement for voltage regulation comprising: an input connection for supplying a supply voltage; an output connection for tapping off an output voltage; an output stage comprising a control input and a controlled path having a first and a second load connection, the first load connection being coupled to the input connection, and the second load connection being connected to the output connection and being coupled to a reference potential connection via an electrical load; a reference generator, which provides the reference potential at its output; a comparator, which comprises a first input connected to the reference generator a second input coupled to the output connection for regulating the output voltage; and an auxiliary regulator for limiting the voltage drop across the output stage, comprising a control element that couples the input connection to the controlled path of the output stage at a circuit node and comprising a further comparator having a nominal value input, which is coupled to the control input of the output stage, and having an actual value input, which is coupled to the circuit node.
