PRELIMINARY DATA
DESCRIPTION
The L4918 combines both a filter and a voltage regu-
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 output transistor from saturation at low input vol
tages.
The non linear behaviour of this control circuitry al-
lows a fast setting of the filter.
