Abstract
A circuit, method for regulation, and use thereof is provided, whereby the circuit can include a charge pump that is connected to a supply voltage terminal in order to produce a pump voltage from a supply voltage, and includes a control circuit whose inputs are connected to the output of the charge pump and to the supply voltage terminal in order to sense a difference between the pump voltage and the supply voltage as a controlled variable. The circuit is designed to compare the controlled variable to a reference variable, and output is connected to a control input of the charge pump in order to control the charge pump as a function of the comparison.
