Hi all,

do you have any idea guys how the internal volatage regulator works ?my board is working  only if my input voltage is 2.5V  (the MinProg4 is also suppling power to my board) if I cahnge it to 5V or 3.3V in the PSoCprogrammer my board stops working do you have any idea how the internal volatage regulator works. I need at least 3.3V supply volatge ,because I have othe ICs on my board  that works with min 3.3V.

Thanks

Hi Esey,

Are you using your custom board ? In that case could you please make sure that the connections in the power pins are proper for internal regulator mode. Please refer Power section in PSoC 4 Hardware Design Guide.

Best Regards,
