Abstract
A voltage regulator comprising a reference current generator coupled between a supply terminal and a reference terminal and configured to provide a reference current that is independent of an operating range of a supply voltage; and a regulator stage comprising: a current terminal configured to receive the reference current; a NMOS transistor having: a gate coupled to the current terminal; a drain coupled to the supply terminal; and a source coupled to an output terminal; a voltage reference circuit for providing a regulated output voltage coupled between the output terminal and the reference terminal, the voltage reference circuit comprising an output resistor coupled in series with a conduction channel of an output bipolar transistor arranged in a diode-connected configuration; an input bipolar transistor having: a conduction channel coupled between the current terminal and the reference terminal; and a base terminal coupled to a base terminal of the output bipolar transistor.
