Patent ID: 8536934

Claim:
A linear voltage regulator comprising: a voltage reference to generate a reference voltage; a pass transistor coupled between an external power source and an output terminal of the voltage regulator, an output of the linear voltage regulator being provided at the output terminal; a voltage divider network coupled between the output terminal and a constant reference potential; a first amplifier to compare the reference voltage and a voltage at a first node in the voltage divider network and to control an impedance of the pass transistor; and a second amplifier to compare an output voltage of the output and a voltage at a second node in the voltage divider network and to inject a current into the first node, wherein the current is proportional to a difference of the output voltage and the voltage at the second node, wherein the absolute value of the voltage at the first node is greater than the absolute value of the voltage at the second node, wherein the magnitude of the output voltage is less than the magnitude of the reference voltage.
