ABSTRACT:
Circuit arrangement for voltage regulation having a differential amplifier having first and second inputs and first and second outputs, wherein a reference voltage is applied to the first input and a voltage to be regulated is applied to the second input. A charge pump is connected to the first output of the differential amplifier. A current mirror is connected to the second output of the differential amplifier. A transistor, which influences the voltage to be regulated, has its control input connected to the current mirror and the charge pump.
