TPS7B7702-Q1: Ground Shift for Antenna specification

Part Number:TPS7B7702-Q1

Hi,

One question: For the TPS7B7702-Q1 my customer has the specification that if their is a ground offset of +/- 1V, the Antenna supply LDO needs to work properly.

1. So does the TPS7B7702-Q1 supports a +/11V GND-Offset?

2. Does all the diagnostic features (particular the short-circuit function works properly with such an GND offset (especially for -1V)?

To my understanding, as long as the voltage potential shift (with reference to GND) does not exceed the abs. max. ratings or the recommeended operating ratings) we should be fine. Critical should only be the condition when the internal ESD structures get's triggered by getting lower then -0.3V with refernce to GND.

But I would like to get this double checked!

Thanks in advance
