Hello everyone. I have a doubt about the power supply system available in Caravel, because I have searched for documentation about power information and I haven't found detailed info about it. I understand that all user area power supplies are provided by voltage regulators on the development board. But I didn't found information about regulators specifications (e.g. Max Current provided, schematic). Does anyone know where I can find such information?

We got no circuit IP from SkyWater for voltage regulators, so there are no voltage regulators on-chip. The two regulators are on the demonstration board, generating 3.3V for VDDIO, VDDA, VDDA1, and VDDA2; and 1.8V for VCCD, VCCD1, and VCCD2. I can look up the part numbers for you if you need them (also check the #caravel-board channel).

LDO P/N is https://www.microchip.com/en-us/product/MIC5350 from https://github.com/efabless/caravel_board/blob/main/docs/Caravel_Board_Specs%20_clean.pdf
