Abstract (en)
[origin: EP0838746A1] The voltage regulator has an input terminal (EL) which is connected to a supply voltage (VL). A reference generator circuit (1') delivers a reference voltage (VBG) which is proportional to the required regulated output voltage (VR). An amplifier circuit (2') amplifies the error signal between the reference voltage and the actual output voltage to produce a constant of proportionality. A capacitor (C) is connected across the output of the regulator to sustain the output voltage temporarily and the energy stored in the capacitor is used to temporarily supply the regulator circuit if the supply voltage falls. A comparator (12) delivers an external logic signal if the supply voltage falls.
