11/26/2023, 8:19 PM@Tim Edwards I'm planning to create a different repo for successful silicon

11/26/2023, 8:21 PM@Tim Edwards I have a problem now testing a larger LDO that supports 100mA loads on MPW3 as the enable output is a digital input that needs to programmed by Nucleo board. The problem that nucleo board interfere with the analog pins of the LDO.

11/26/2023, 8:21 PMAny ideas how to deal with that?

11/26/2023, 8:29 PM@Amro Tork: I can't understand the nature of the problem without a user project wrapper and the repository you linked to above doesn't have one.
Does the problem happen during calibration or afterward? If afterward, it should be possible to put the Nucleo pins into a tri-state mode.

11/26/2023, 8:36 PM@Amro Tork: Sure.
For the repository you pointed to above, there are four LDO schematics (Folded and Miller, 1.8v and 2.2v). Which one are you looking at in the oscilloscope photo above?

11/26/2023, 9:54 PMI'll create a separate repo for that LDO that we have tested that include the GDS, netlist and everything.
