Patent ID: 7019562

Claim:
A circuit, comprising: a power-regulating circuit adapted to respond to a power supply voltage by providing an operating current and an operating voltage to a common node, the power-regulating circuit including, a current mirror adapted to provide the operating current to the common node; and a load coupled between the common node and a reference supply and adapted to conduct a first portion of the operating current and, therefrom, establish the operating voltage at the common node, the load including, a resistive element having a first conductor coupled to the common node; and a voltage source coupled between a second conductor of the resistive element and the reference supply; an input stage coupled to the common node and adapted to conduct a second portion of the operating current; an output stage coupled to the common node and adapted to conduct a third portion of the operating current; and a stabilizer coupled to the common node and adapted to provide a compensation current to the common node to stabilize the operating voltage at the common node in response to differences between a first reference voltage and a feedback voltage indicative of variations at the common node.
