Hi, I'm trying to use the FT234XD for both the power supply and USB-to-Serial for my device. The device will draws less than 15 mA.
I've tested the FT234XD (from Digikey) chips on my board, it produces 3.86V with and without the load connected.
We also ordered UMFT234XD dev boards. These work well, connected to the load and without they provide a nice stable 3.3V supply.
What could be the problem? Are there some settings that we're missing?
