PRELIMINARY DATA
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.
A supervisor 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.
