Electronic circuit for supplying a voltage

An electronic circuit for supplying a voltage, said electronic circuit including

• a plurality of supply circuits, each of said supply circuits including a source (B1, B2, . . . , Bn) of electric current and transistors (T10,T11;
• T20,T21;
• . . . ;
• Tn0,Tn1) connected with said source (B1, B2) of said electric current to form an analog switch for gating said electric current, each of said transistors having a gate electrode;
• means for electrically connecting said transistors in each of said supply circuits with a common output terminal (KI.U) at which a supply voltage (UV) is provided for at least one consumer connected with said output terminal;
• a switch (Z) connected electrically between a current supply and the gate electrodes in each of said supply circuits by means of at least one resistor and at least one other transistor;
• and
• a microprocessor (.mu.C) connected with said gate electrodes of said transistors in each of said supply circuits, said microprocessor (.mu.C) including means for changing a potential at each of said gate electrodes;
• whereby said supply voltage (UV) is provided by one or another of said supply circuits according to said microprocessor (.mu.C) and said switch (Z).
