SPC5 and L9907 current budget recommended?

[CTara]

Hello!

I am developing a motor controller driver running on a 48V Li-Ion battery. I want to choose the right regulators. Unfortunately I can not use the MCTK-01 as reference because it is supplied via the mains.

What is the current budget I should plan for the SPC5?

_________________________________________________ L9907?

Which voltage do you recommend to choose to run both or not? 3V3 or 5V?

Thanks in advanced for your lights.

Cheers,

Christophe
