Abstract
A regulator for providing a load current at a regulator output voltage to a load at an output of the regulator is described. The regulator has a differential input stage to provide a differential output voltage based on a reference voltage and based on the regulator output voltage. Furthermore, the regulator has an output driver to generate a control signal based on the differential output voltage. In addition, the regulator has a pass transistor to provide the load current in dependence of the control signal. The regulator also has clamping circuitry to sense an overvoltage indication which indicates that the pass transistor is being turned off. Furthermore, the clamping circuitry clamps the differential output voltage to a clamping voltage, if the overvoltage indication indicates that the pass transistor is being turned off.
