Hi All,
Can anyone remind me? I recall that one can only test an LR8 regulator under load and not without. Is that correct?

Hi David, I posted this in the other thread

"Hi, A good question. I am not sure, but I always do. If you have it out of circuit then a small load ought to be fine. Calculate what a 1ma load would be and use that value resistance. Be careful not to short it out when testing as they have a tendency (like about 90% of the time) to fail immediately without warning."

Good listening
