ABSTRACT:
A voltage regulator and regulator buffer having a plurality of matched transistors including an output transistor arranged such that the fluctuation in supply voltage is sensed by a shunt circuit which tracks such voltage fluctuation and eliminates such fluctuations from the output transistor by causing current variations due to supply voltage variations to flow through another transistor connected in parallel with the output transistor thus eliminating the first order effects of power supply voltage variations on output voltage. The voltage regulator buffer comprises a plurality of matched transistors which also has a voltage supply variation shunt circuit similar to the regulator shunt circuit to regulate the current through an output transistor thus eliminating the effect of the power supply voltage thereon and providing an output voltage of a precise amount.
