Semiconductor voltage follower arrangements adapted for construction in integrated circuit form. A load circuit is coupled to the emitter of a voltage follower transistor. Operating potential is supplied to the collector of the follower transistor via the base-emitter circuit of a second transistor arranged in a common emitter transistor. The collector-emitter circuit of a regulator transistor is coupled across the load circuit. Feedback is provided from the output of the common emitter transistor to the input of the regulator transistor such that the collector current of the follower transistor is substantially independent of input voltage variations applied to the base of the follower transistor.
