Positive input voltage range for an LT1006 is typically 1.2V below the
positive rail.

Subject: [volt-nuts] LTZ1000 reference appnote question
Hello, in this thread on eevblog:
http://www.eevblog.com/forum/projects-designs-and-technical-stuff/does-anyone-know-what-this-diode-is-for/
a guy named DiligentMinds.com asked the question
about why there is a 1N4148 diode on the output of
the opamp in the LTZ1000 reference circuit, the one
designed by Jim William in the appnotes, that can
also be seen on the first page of the datasheet:

Now I'm curious,
anybody knows the answer?
Thanks,
Fabio.
