REGULATOR CIRCUIT AND SEMICONDUCTOR MEMORY APPARATUS HAVING THE SAME

摘要

A regulator circuit may include a comparison unit configured to compare a reference voltage with a feedback voltage and generate a first switching signal. The regulator circuit may include a current supply unit configured to receive a pumping voltage, and determine a level of a second switching signal in response to the first switching signal. The regulator circuit may include an output driver configured to control the level of the second switching signal in response to an output voltage, receive the pumping voltage, and generate the output voltage in response to the second switching signal. The regulator circuit may include a feedback signal generation unit configured to detect a level of the output voltage and generate the feedback voltage.
