ABSTRACT:
A band-gap voltage regulator having a self-regulating characteristic which improves the operation of the regulator includes a feedback circuit coupling a gain stage of the regulator to a voltage reference circuit which influences the regulated voltage. Changes in the operation of the gain stage which would otherwise change the regulated voltage produce counteracting changes in the voltage reference circuit, causing the supply voltage to remain substantially constant.
