ABSTRACT:
A low voltage regulation circuit especially suitable for supplying current to high frequency loads is provided. The circuit comprises two P channel MOSFETs having the same threshold voltage and two N channel MOSFETs having repsectively different threshold voltages. The difference between the threshold voltages of the two N channel MOSFETs is provided as a constant output from the circuit, and load current is supplied from the output terminal. Circuit construction is simplified such that a low voltage regulation circuit with a small pattern area on the integrated circuit is obtained.
