As long as you work within the limits of the device they are very hard to kill. I have used them with a similar regulator in an automotive enviroment with an rs232 tranciever. And after 3 years of operation the only thing that killed one was a bus being caught in a flood for a week. Though i was using an LDO to 3.3V to power the micro and rs232 | |

Their output ripple and ability to power capacitive loads or deal with start up inrush currents leave much to be desired. I have a board in front of me that uses a R-78C5.0-1.0 to power a MAX232 which fails to come up reliably unless the MAX232's outputs are disconnected at startup. | |
