ADP3339 minimum input power and tolerance

According to the datasheet ADP3339 has a 2.8 V to 6 V input voltage range. We currently use this device in our design which feed in only 2.48V at the input due to design limitation. I understand that this is not ideal but so far we have minimal fall-out. Without specifying in a new part, could someone please explain the impact of providing insufficient input power and the risk/failure symptoms?

Thanks.

  • Hi Peter,

    Apologies for the delayed response, I'm still securing the board and ICs. Looking at this again though, I'd agree with Harry. It would be better to look at possible replacement parts that you could use in your circuit, pls see attached excel file, it contains information on several ADI ICs that you might want to use instead. For example, you can use the ADM7171 or ADP1752 for the DVDD_1.8V and ADP121 or ADP150 for the CVDD_1.8V.

    Best regards,

    Jess
