XIO2001: Maximum power consumption, the worst case

Genius 15690 points
Part Number: XIO2001
Other Parts Discussed in Thread: TPS726

Hello,

 

I have read some similar questions on other E2E posts,

but I would like to know maximum current consumption for 1.5V of XIO2001 to select reasonable power device.

It seems to highly depends on the use case. But what I want to know is the worst case.

There is nominal power consumption data in the datasheet(SCPS212i), 6.5 on P17.

The below is the from the table in the datasheet.

Can we think that the below case is the worst case?

  

Our reference schematic in “XIO2001 Implementation Guide” (SCPA045D) uses 1A class LDO(TPS726).

Should the user prepare 1A class if thinking of worst case?

Regards,
Oba
