Can the LT1389 work reliably below 0C? The datasheet says a low end operating temperature range of 0C but a few of the test figures show data at -40C.
You're welcome! Glad that was helpful.
Before I answer your questions, I have to correct something - I misspoke when I said the output PMOS was a low-impedance current source, it's actually a high one dynamically, although its Rds,on is…
