Hi
LM3880 Simple Power Sequencer datasheet (Rev. M)
LM3880MF-1AE/NOPB is a power supply sequencer IC with a fixed 2ms time interval.
However, when confirming the Timer delay 1 accuracy parameter, it was found that there was a 20% error.
What could affect this error value?
Recommended circuits in the data sheet is used as below.
The rise time of the EN pin is 20ns(Max).
Thanks and Best Regards
