A circuit for regulating an output voltage of a charge pump includes a regulator connected to an output of the charge pump. The regulator includes a voltage divider for dividing the output voltage. A filter has a first input for receiving the divided output voltage, a second input for receiving a control signal, and an output for providing a filtered divided output voltage. A comparator has a first input for receiving the divided output voltage, a second input for receiving a reference voltage, a third input for receiving the filtered divided output voltage, and an output for providing a digital signal based upon a comparison of the divided output signal, the reference voltage and the filtered divided output voltage. A logic control circuit has a first input for receiving a clock signal, a second input for receiving the digital signal from the comparator, and an output for providing a timing signal. A phase generator circuit has an input for receiving the timing signal from the logic control circuit for generating control phases for the charge pump.
