ABSTRACT:
A complementary field effect transistor integrable voltage regulator suitable for use in CMOS integrated circuits includes first and second regulator sections coupled together. One regulator section includes a P channel MOSFET and an N channel MOSFET and a resistor, the P channel MOSFET and the resistor being coupled in series between an internal supply conductor and a reference conductor, the N channel MOSFET being connected in parallel therewith and having its gate electrode connected to the junction between the P channel MOSFET and the resistor. The gate electrode of the P channel MOSFET is connected to the output of another regulator, which includes a zener diode and a resistor coupled in series between the reference conductor and another voltage conductor.
