1. A voltage regulator comprising:
three voltage regulator connections one connection being an input voltage connection, one connection being an output voltage connection and one connection being an ground connection, an output circuit having an input connection, the output circuit being connected to the input voltage connection and to the output voltage connection, a differentiating circuit having a differentiating output and an input, the input being connected to one of the voltage regulator connections, and an amplifier having an amplifier input and an amplifier output, the amplifier input being connected to the differentiating output and the amplifier output being connected to the input connection of the output circuit, the differentiating circuit being designed to detect a voltage at its input and to provide it as a differentiated signal at its differentiating output, and the amplifier being designed to inject a compensation signal dependent on the differentiated signal into the input connection of the output circuit of the voltage regulator, the amplifier having a first output stage which is designed to inject a positive part of the compensation signal into the input connection of the output circuit, and the amplifier having a second output stage which is designed to inject a negative part of the compensation signal into the input connection of the output circuit, the amplifier further having a first voltage source and a second voltage source and a first resistor and a second resistor, the first voltage source being connected, by means of the first resistor, to the input of the first output stage of the amplifier, and the second voltage source being connected, by means of the second resistor, to the input of the second output stage of the amplifier. |
