According to the invention, a buffer capacitor (4) is connected, on the one hand, via a series controller (5) limiting the charging voltage of the buffer capacitor (4), to supply voltage terminals (2, 3) and, on the other hand, via a voltage stabilizing circuit (6), to lead terminals (1a, 1b) of the electronic device (1). Thus the buffer capacitor (4) can be charged to a charging voltage which is clearly above the operating voltage of the electronic device (1), so that the period until the minimum operating voltage of the electronic device (1) is reduced, is lengthened. In addition, a constant operating voltage is available for the electronic device (1).
