Abstract:
A voltage-regulator circuit with a current-adder output node for supplying a load with a load current at a regulated output voltage includes an analog portion sensitive to the output voltage and including one or more reference-voltage sources. The analog portion applies to the current-adder node a first current that is a function of the difference between the output voltage and the reference voltage. A digital portion including an integrator is sensitive to the first current. The integrator is coupled to a current source for applying to the current-adder node a second current so that the first current and the second current supply on the current-adder output a load current at the aforesaid regulated output voltage.
