Pololu D24V5F3

These are really nice power supply modules from Pololu..

They run from anything up to 36V and regulate down to a nice 3.3V. They cope if I reverse the polarity. They are tiny (0.4″ × 0.5″). They just work.

They cost a few dollars, and actually cost more than the ESP32-WROOM-32 (at current pre-brexit style exchange rates), but they really just work, and I am using them everywhere.

What I did not work out, when ordering a 100 of them, is that they are so recyclable! I am changing controllers from ESP8266 to ESP32, but the power modules can be easily desoldered and re-used. I have so many I am thinking of listing them on Amazon.

I whole heartedly recommend them, very nice, work well, don't get fried when you cock up.
