EG512R-EA current consumption

Tell me, what is the maximum current consumption for the EG512R-EA modem together with the FG50V module?

The power supply of EG512R-EA module should be able to provide sufficient current of
3.0 A at least for 3.8V.
The RF power supply of FG50V module should be able to provide sufficient current of
1.3 A at least for 3.8V.
The other voltage of FG50V comes from EG512R, and the other current loss of FG50V is included in the maximum current consumption of EG512R

Thank you. The documentation states that these are peak currents. Is it permissible to connect both lines to a stabilizer with an average current of 3A and a peak current of 5A?
