Problems using the ADM7155

Hi Sancho_Pansa,

Can you please share more information about your circuit such as your schematic, package marking, etc? This is for me to properly help you the problem you're encountering.

Thanks,
Alex

Hello Alex,

Thank you for feedback

The circuit is: ADM7155ARDZ-02-RZ.

The schematic is as in datasheet.

Here it is:

R1 = 28.1k

R2 = 18.7k

EN is connected to Vin

Vin = 3.3V

I want 3V at output but instead I have 2.56

Well, I didn't connect Cin, Cout, Cref, but I suppose that they cannot have such impatct on Vout

The package: SO-8

Hi Sancho_Pansa,

Thanks for these info, may I also know what is the ADM7155 model that you are using? Is it ADM7155ARDZ-04-R7?
