This circuit combines both a filter and a voltageregu-

lator in order to provide a high ripple rejection over a

wider input voltage range.

A supervisor low-pass loop of the element prevents

the outputtransistor from saturation at low input volt-

ages.

The non linear behaviour of this control circuitry

allows a fast settling of the filter.
