Why would they put a precision voltage reference in the same package as an LDO?

The application  notes are full of examples where an LDO is used as the protected output device on a precision regulator.

Semiconductor manufacturers make integrated circuits that they can sell in huge volumes. Collaborators with physicists have the task of using them to do the jobs that a very few physicists want done.
