Dear, On the KIT MAX R 10 10M08 Eval Kit Board is it possible change the voltage of the regulator EP5388QI from 3.3V to 2.5V? The VCC_CORE can be 2.5V for the proper operation? I not using the Arduino or Opamps circuits from this board.

Dear,

On the schematic of the Kit there are a regulator called U1(PN> EP5388QI), on this regulator is connected VCC_CORE and VCC_IO.

I need 2.5V on the VCCIOs but on this design of board there are just one regulator and if i change the voltage in this regulator(U1) the voltages of VCC_CORE and VCC_IO will be change together.

What You sugest to change the voltages on VCC_IO to 2.5V on this KIT?

Best regards,

Dan

​Hi Dan,

Okay, It depends on Output voltage select pin 10,11,&12.

The regulator section board is designed by selecting one of seven preset output voltages here it is 3.3V, not by choose external divider.

I don't think we can change the voltage.
