Abstract
A circuit includes an input stage configured to receive a regulated input signal and generate an input stage output signal in response to the regulated input signal. An isolation stage can be configured to pass the input stage output signal to a buffered output node. The isolation stage receives feedback from the buffered output node to deactivate the buffer input stage if transient voltages are generated at the buffered output node. An output stage can be configured to provide current to the buffered output node in response to the regulated input signal.
