ABSTRACT:
A voltage reference circuit for producing a predetermined output voltage at an output thereof having good output voltage regulation and which includes a diode bias string and a transistor having its base-emitter path coupled via a diode between predetermined ones of the diodees comprising the diode bias string. The output of the voltage reference circuit is taken at the emitter of the transistor. The voltage reference circuit presents a low impedance at the output thereof and is capable of both sourcing and sinking current thereat over a wide range of current values.
