Abstract: A digital low drop-out regulator circuit includes transistor switches that are selectively actuated in response to a comparison of an output voltage at an output node to corresponding tap reference voltages. A dynamic reference voltage correction circuit operates to shift voltage levels of the tap reference voltages in response to a difference between the output voltage at the output node and an input reference voltage.
