L4916 - VOLTAGE REGULATOR PLUS FILTER

Description

This circuit combinesboth a filter and a voltageregulator in order to provide a high ripple rejection over a wider input voltage range.

A supervisor low-pass loop of the element prevents the outputtransistor from saturationat low input voltages.

® L4916 VOLTAGE REGULATOR PLUS FILTER . . . . . . . . FIXED OUTPUT VOLTAGE 8.5 V 250 mA OUTPUT CURRENT HIGH RIPPLE REJECTION HIGH LOAD REGULATION HIGH LINE REGULATION SHORT CIRCUIT PROTECTION THERMAL SHUT DOWN WITH HYSTERESIS DUMP PROTECTION DESCRIPTION This circuit combinesboth a filter and a voltageregulator in order to provide a high ripple rejection over a wider input voltage range. A supervisor low-pass loop of the element prevents the outputtransistor from saturationat low input voltages. The non linear behaviour of this control circuitry allows a fast settling of the filter.
