Part Number: LM7800
I am testing it in a climatic chamber in order to be sure that the regulation is done properly.
Beside regulation there could be any other problem?
In the next production we will switch to a new component (extended), but we would like to send some of our boards to North pole.
Thanks in advance
LM7800 was designed, tested, and characterized for operation down to 0 C. Below 0 C the performance of the regulator may or may not meet the performance depicted in the datasheet. As you suspect the most likely specification for you to notice a shift is regulation accuracy.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
