Overview

L4918 VOLTAGE REGULATORS PLUS FILTER .
.
.
PRELIMINARY DATA FIXED OUTPUT VOLTAGE 8.
5V 250mA OUTPUT CURRENT HIGH RIPPLE REJECTION HIGH LOAD REGULATION HIGH LINE REGULATION SHORT CIRCUIT PROTECTION THERMAL SHUT DOWN WITH HYSTERESIS DUMP PROTECTION 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 vol tages.
The non linear behaviour of this control circuitry allows a fast setting of the filter.
