Abstract (en)

[origin: WO02052364A1] The invention concerns a voltage regulator having an output terminal (S) designed to be connected to a load (R), comprising an operational amplifier (4) whereof the non-inverting input is connected to a first reference potential (Vref), and whereof the inverting input is connected to the output terminal (S), and inverting stage (6) whereof the input is connected to the operational amplifier output, a power switch (T1) controlled by the inverter stage (6) output, arranged between the output terminal (S) and a supply potential (Vbat), and a load capacitor (C) arranged between the output terminal (S) and a supply reference potential (GND), including means (7) for reducing the effective output impedance of the operational amplifier (4).
