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. -- Bill Sloman, Sydney
