Abstract (en)
[origin: EP0915408A1] This invention relates to a high voltage regulator partly supplied by a boosted voltage (PUMPOUT) and adapted to deliver a regulated output voltage (Vout) on an output terminal (OUT), starting from a sampled voltage (Vsample) obtained by dividing the regulated output voltage (Vout), which regulator comprises at least a comparator element (2) being supplied a supply voltage (Vdd) and feedback connected to a divider (4) of the regulated output voltage (Vout), the divider (4) being a diode type of divider connected between the output terminal (OUT) and a first comparison voltage reference (GND, Vref_v) and having a central connection node (Y, Z) connected to a non-inverting terminal of the comparator element (2). The invention also relates to a method of regulating a voltage (Vout) derived from a boosted voltage (PUMPOUT), comprising the steps of: obtaining a sampled voltage (Vsample) as the voltage value at a central connection node (Y, Z) of a diode type of divider (4) connected to a reference of the voltage to be regulated (Vout) and connected to a first comparison voltage reference (GND, Vref_v); regulating this voltage (Vout) according to the comparison of said sampled voltage (Vsample) with a second comparison voltage reference (Vref_v, GND). <IMAGE>
