Abstract (en)
[origin: EP0795808A1] The parallel regulator has a controllable semiconductor in the form of a Darlington pair of n-p-n transistors (1,2) with emitters interconnected by a resistance (3). The emitter-collector paths interconnect the two output terminals (4,5). The reference input (25) drives the base of an emitter-follower (27) in cascode with a constant-current source (14-16) feeding a regulating amplifier of the actual-value input (30). A bias current is supplied in accordance with the difference between the actual-value and reference voltages.
