I might have to clarify: I'm not saying that the IC has a problem and that
I don't recommend it for projects. As I said, it works very well.
The manufacturer itself has set the status to "not recommended for new
designs", they have developed a new version.

Or just bad luck. I don't think there is a generic design problem. Usually
and in particular when I have been moving around - I touch some ground
first to discharge myself just to be on the safe side...

yes, the schematic in the datasheet. I hope it will work as expected, I
already ordered some new boards.

I was using the datasheet schematic of the MP1584 regulator. The FB divider
for 3.3V is 124k to Vout and 40.2k to ground. The regulator works great but
now is no longer recommended for new designs anyway.
I switched to AP63203WU-7 for 3.3V and AP63205WU-7 for 5V. The design is

Ah, this is not uncommon. A lot of AVR Dragons were slain for the same
reason. Touching the regulator affects its feedback and therefore its
output voltage. A tiny ESD, not enough to cause any damage, can drive the
output high for enough milliseconds to cook a 3.3V IC downstream.
On Wednesday,
The voltage feedback resistor is a low impedance node on every voltage
regulator design that I have worked with. Typically 1k ohm. I don't see how
that could happen.

I just wanted to share something that happened to me yesterday. I killed
the ESP32 on my nixie board just by touching the adjustable voltage
regulator IC with one finger. I’m pretty sure that I touched the feedback
pin causing the voltage to increase.
I already changed the design, and, in the f
