DESCRIPTION

The L4918 combines both a filter and a voltage regulator 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 voltages. The non linear behaviour of this control circuitry allows a fast setting of the filter.
