VOLTAGE REGULATOR PLUS FILTER
........ FIXEDOUTPUT VOLTAGE8.5 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 voltageregu-
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 outputtransistor from saturationat low input volt-
ages.
The non linear behaviour of this control circuitry
allows a fast settling of the filter.
