The UTC CW574 is a parallel voltage regulator which provides stable harmonious voltage for high frequency tuner
head of color TV.
The main power 115V goes through Rs resister to position 2 of UTC CW574 then the position A with 33V
provides stable voltage for control circuit of high frequency tuner. The circuit from R3 to R10 is potential meter for
tuning, according to different channels to change contact positions; to provide corresponding voltage to tuner; and to
control the capacity of varicap diode in order to have high frequency tuner into proper channel.
The voltage range of UTC CW574 is required to cover necessary frequency range, and main issue of UTC
CW574 is its reliable voltage stability which avoids unexpected frequency offset; therefore, the circuit of UTC CW574
contains temperature compensation to have lowermost temperature coefficient
.
