Thanks so much - I was hoping that was the case, it will save a lot of time..The voltage regulator on the Pico is a switching buck/boost circuit that can accept between 1.8V and 5.5V on VSYS and supplies 3.3V to the RP2040. It is very efficient, so produces little heat. Using an external 3.3V regulator probably wouldn't save you anything.
Just to double check - presumably I can also (alternatively) connect my 5v power supply pin to the Pico's USB port (or USB-C port on a clone) using a cable like in the original post
