Hi,
In playing with some oscillators and a GPSDO here, I think I'm seeing a
voltage sensitivity issue.
So, I started looking at the output voltage of various regulators vs.
temp. Using standard LM/UA type linear regulators and some LDO's, they
all appear to be pretty sensitive to temperature. (millivolt / few
degrees Fahrenheit sort of sensitivity). Most of the datasheets seem to
ignore temp sensitivity. Almost like they are so bad they don't want to
publish it...
Does anyone have hints on TO-220 or D-Pak type regulators that have
really good temp coefficients and good line regulation? A few PPM/Deg C
might be nice, if possible. Or am I into a 'roll you own' type design...
Dan
