The circuit comprises the following parts: a pre-regulator whose purpose is to give a KVBE voltage as small as possible sensitive to the variations of the power supply VPP and to allow a low impedance for the driving of the output E.F. This impedance is such that for a noise transmitted by CCB of Ts, the output E.F. transistor works like a base grounded transistor and is very fast, a voltage reference to drive the regulator, an output E.F. giving the power and the lowest possible output resistance when the loop is open, the amplifier of the regulator driving both the base of the output E.F. and a variable current source, a current gain compensation can be added in some cases.
