DESCRIPTION
TheL4918combinesbothafilterandavoltageregu-
latorin order to providea high ripple rejectionover a
wider input voltagerange.
A supervisorlow-pass loop of theelement prevents
the output transistor from saturationat low input vol
tages.
The non linear behaviourof thiscontrol circuitry al-
lows a fastsetting of the filter.
