15, reverse bias sources are included that are included in the basic circuits of one or several transistors of the regulating element, except for the first matching, and passive nonlinear elements, for example, diodes connected separately in parallel to the circuits formed in series by the connected sources. 39 by reverse bias and collector transitions of the respective transistors of the regulating element. In addition, in order to simplify, the reverse bias sources are made on resistors. The drawing shows a schematic diagram of a voltage regulator. The voltage regulator contains a series composite regulating element consisting of the main transistor 1 and additional transistors 2 and 3, the collectors of which are connected respectively to the terminals of the main C and additional sources 5 and 6 of the power supply. The control unit (node) 7 is connected to the base of transistor 3 with its output. The base circuits of transistors 1 and 2 include sources of reverse bias, respectively, 8 and 9 - Nonlinear elements - diodes 10 and 11 are connected in parallel to the circuits formed by series-connected sources displacement and collector transitions of transistors 1 and 2. The device operates as follows. At the maximum input voltage, the diodes 10 and 11 do not pass the current and the stabilizer works like a normal linear regulator with the power supply of matching transistors 2 and 3 from additional power sources 5 and 6. At the minimum input voltage, the transistors 1 and 2 are saturated and the stabilizer performs its functions using a transistor 3 controlling the control unit 7- The saturation state of these transistors is maintained by the ratios of elements 8 and 10, 9 and 11. Thus, the stabilization is effective, especially for low-voltage direct current circuit. When the load current changes, the stabilization principle does not change, and node 7 is always loaded on the first of the composite transistors. 3 The invention allows for expanding the functionality of a voltage stabilizer with changes in the ratios of the voltages of the supply sources.
