QPA9122 power issue

We are using QPA9122 in one of our IC’s and as per the datasheet an 8.2E is in series at the VCC1/VCC2 pin which causes an IR drop of 1.37V in our design. Is it expected or what should be done for the same

I would say that is intentional. If you are using the recommended supply voltage Vcc (5V) follow the recommended schematic.
