Abstract
A voltage regulator circuit which provides a regulated output voltage by regulating output current at an output terminal is provided. The voltage regulator circuit operates in response to a clocked control signal. The regulated output voltage and a delayed signal of the regulated output voltage are both used to bias a selected one of series-connected transistors which sink current from the output terminal in response to the value of the output voltage and the frequency of the clocked control signal. A second control signal is provided for enabling or disabling the voltage regulator circuit.
