Any chance that it started oscillating? What decoupling caps do
you have on the input and output of the regulator? About the only
regulator I can recall being dud was one that was out of spec at
power-up. Something like 13V instead of 12V. I don't remember
the brand now - was some time ago. If your decoupling is all ok I
reckon you were just unlucky. Doubly so for it failing right in front
of the customer!  Murphy must have been at his place, not yours.
