ABSTRACT:
A voltage regulator circuit for regulating an input voltage supply. The voltage regulator includes an n-channel transistor that has a gate and a source/drain region. The source/drain region of the transistor provides an output signal for the regulator circuit. The regulator circuit also includes a pull-up device that is coupled between a pumped voltage supply and a gate of the n-channel transistor. A pull-down device is also coupled between the gate of the n-channel transistor and ground potential. The voltage regulator also includes a level sensing circuit that is responsive to the gate of the n-channel transistor. The level sensing circuit generates a control signal for a control input of the pull-down device to provide feedback control of the n-channel transistor to regulate the output of the source/drain of the n-channel transistor.
