ABSTRACT:
A circuit is shown in which a voltage regulator has an output stage that operates as a Darlington when the input-output differential exceeds a threshold. The circuit automatically switches to a common emitter output and an emitter-follower driver when the differential falls below the threshold. A current limiter prevents excessive common current when the output transistor is saturated.
