Abstract:
A method of operating a voltage regulator circuit includes generating a control signal by an amplifier of the voltage regulator circuit. The control signal is generated based on a reference signal at an inverting input of the amplifier and a feedback signal at a non-inverting input of the amplifier. A driving current flowing toward an output node of the voltage regulator circuit is generated by a driver responsive to the control signal, and the driver is coupled between a first power node and the output node. The feedback signal is generated responsive to a voltage level at the output node. A transistor, coupled between the output node and a second power node, is caused to operate in saturation mode during a period while the voltage regulator circuit is operating.
