RF 3GPP compliancy requires 3.3V.

[SODAQHW]

Hi,

I have a question about the tolerance on the VDD voltage. In the datasheet it says: "RF 3GPP compliancy requires 3.3V."

I am wondering if there is more specific information available on this note, because we get short dips in our VDD Voltage (3.3V) when sending LTE-M messages and a large current is drawn.

How stable must this 3.3V level actually be to ensure reliable operation and 3GPP compliancy?

Is 3.3V the absolute minimum or are small dips of a certain dropout voltage and certain duration allowed? What are these values.

Hope to hear from you soon.

Kind regards,

Hi Jonathan,

Thanks for the quick reply and information.

That is good to hear, generally our supply voltage doesn't dip under 3.1V, so I think we're okay.

This case can be closed now.

Kind regards,
