Dear Support and Expert,
I have a design which has an intermittent problem which may relate to the LM78L05 , as shown in the waveform, the dark blue is 12V input, the pink is 5V output,
the observation is that after the input voltage over ~3.5V, the output of the LM78l05 starts to output ~2.4V until the input voltage is over 7V, the output starts to regulate to 5V.
I couldn't find a chart of the power-on transient on the datasheet, is this startup waveform make sense?
Best Regards,
David Sun
