Abstract: The generator of reference voltage comprises a first generator of current (1) suitable for generating a first current (I) that varies linearly with the supply voltage, a first generator of voltage (T10, T11, R4, R6, T6, T7, I3, T12) suitable for generating a constant first voltage (VBG) with zero thermal drift, a second generator of current (T10, T11, R4, R6, T6, T7, I3, T13, T14, T15, R5) suitable for generating a second current (I1) dependent on said voltage (VBG) with zero thermal drift, a second generator of voltage (T6, T7, T10, T11) suitable for generating a second voltage (DVBE) with given thermal drift, a third generator of current (T6, T7, T10, T11, T4, T5, T8, T9) suitable for generating a third current (I2) dependent on said voltage (DVBE) with given thermal drift and means (5) for combining said currents (I, I1, I2) together so as to produce across an output resistance (R7) an output voltage (Vout) having a value equal to the product of said output resistance (R7) by said first and third current (I, I2), divided by said second current (I1).

Abstract: A voltage regulator (30) comprising a first power switch (16) connected between the input terminal (11) and output terminal (13); a storage condenser (21) connected to the input terminal via a one-way switch (18); a second power switch (19) connected between the condenser and the input terminal; and a regulating element (17) connected to the output terminal and driving the power switches (16, 19) in such a manner as to maintain the output voltage (Vo) constant. For better distributing electric and thermal stress and improving the reliability and working life of the regulator by reducing the interference caused by switching of the two power switches, a drive device (31) is provided between the regulating element (17) and the switches (16, 19), for detecting the input voltage (VA) and the voltage of the condenser (VA'), and keeping both switches on as long as the input voltage is above two given thresholds (VTH1, VTH2), turning off the second switch (19) when the input voltage is higher than the condenser voltage (VA > VA') and below the first threshold (VA
