L4916 : This circuit combinesboth a filter and a voltageregulator 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 saturationat low input voltages. The non linear behaviour of this control circuitry allows a fast settling of the filter.
