Abstract

See full text

A voltage regulator circuit with two series connected resistors connected together at a common resistor node. An initial conducting path has a first pass transistor with a first terminal connected to a first supply rail and a second terminal connected to a regulated output voltage. A main conducting path has a second pass transistor with a first terminal connected to the first supply rail and a second terminal connected to the regulated output voltage. A comparator has an input connected to the common resistor node output is connected to a gate of the first pass transistor. A voltage threshold switch is connected to the common resistor node, and based on the voltage at the common resistor node the voltage threshold switch selectively connects a gate of the second pass transistor to the comparator output.
