DESCRIPTION

This circuit combines both a filter and a voltage regulator in order to provide a high ripple rejection over a wide input voltage range.

Asupervisor low-pass loop of the element prevents the output transistor from saturation at low input voltage.

The non linear behaviour of this control circuitry allows a fast settling of the filter.
