A voltage regulator () comprises a first transistor () which couples an input terminal () of the voltage regulator () to an output terminal () of the voltage regulator () and a second transistor (). The first and the second transistors () form a current mirror structure. Further on, the voltage regulator () comprises a control node () which is coupled to the input terminal () of the voltage regulator () via the second transistor () and which is coupled to the output terminal () of the voltage regulator () via a feedback circuit (). Furthermore, the voltage regulator () comprises an amplifier () with an input terminal () which is coupled to the control node () and an output terminal () which is coupled to a control terminal () of the second transistor ().

Voltage regulator and method for voltage regulation

An amplifier arrangement includes an output amplifier stage (OA) comprising a stage input (SIN), a stage output (SOUT) which is coupled to a signal output (OUT) of the amplifier arrangement, and a capacitive element (CE) which couples the stage output (SOUT) to the stage input (SIN). A driver stage (DR) comprises a driver input (DIN) and a driver output (DOUT) which is coupled to the stage input (SIN). The driver stage (DR) is configured to generate a voltage potential at a driver output (DOUT) depending on an input current at the driver input (DIN) and to provide a charging current to the capacitive element (CE) being higher than the input current.
