ABSTRACT:
A voltage regulator provides a regulated output load voltage at either a positive level or an inverted level relative to an input supply voltage. A switching circuit and control circuit are formed on an integrated circuit having a single pin for coupling to regulator feedback signal. The feedback signal is applied directly to the feedback pin during both positive voltage level regulation and inverted voltage level regulation. The feedback signal may be produced by a feedback circuit comprising an impedance element formed in the integrated circuit.
