I have not seen the regulators fail to keep up with voltage variations. I would suspect that this is a very well designed circuit and should be able to keep up with almost anything. It has a 4.5 volt dropout but the Crio will disable outputs if the battery voltage falls below 5.5 volts. Of course, the Crio is using the 12 volt jumper on the analog module to sense the battery voltage. The fall in all likely hood damaged the internal connector on the bridge.
