I think the original poster was talking about a situation where the output voltage is higher then the input voltage because of an effect OTHER then the regulator. i.e. someone hooking a battery of higher voltage to the output of the regulator. In the case of many linear regulators this would destroy the regulator. TTYL -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
