ABSTRACT:
An error amplifier includes a differential amplifier stage having two inputs and one output. An MOS transistor has a gate terminal connected to the output of the differential amplifier stage, a source terminal connected to a first supply potential and a drain terminal forming an output of the error amplifier. A diode is connected in the conducting direction between the drain terminal of the MOS transistor and a second supply potential.
