Does LMZ20502 start into Pre-Biased loads? If I switch quickly power on/off and output capacitors are still charged does it sink current or is there other problems (mayby broken circuit)?
LMZ21700/01 datasheet says it will start into Pre-Biased loads but problem is that it has min. output voltage 0.9V. We need 0.85-0.89. Is it ok to set output 0.89? Does it cause some problems? With LMZ20501 ot LMZ20502 this is ok because min. output voltage is 0.8V but Pre-Biased start could be a problem.
Any suggestions?
