TPS7A7002: Injecting voltage into the FB pin

Part Number: TPS7A7002

Hi Team,

My customer is asking if they can adjust the output voltage of the TPS7A7002 by injecting a voltage to the FB instead of using a resistor divider.

While it does seem possible to have the appropriate voltage for the comparator in the LDO, I don't see how this would keep the LDO in regulation during transients and different load conditions. Please let me know if my understanding is correct or if you have any other comments. 

Regards, Diego
