DP83867ERGZ-R-EVM: LDO device

Part Number: DP83867ERGZ-R-EVM
Other Parts Discussed in Thread: TPS74701,

Hi Team,

I am checking on behalf of my customer. Pls help to advise for below enquiry, thanks in advance.

From the DP83867ERGZ-R-EVM schematic, it uses two different LDOs - TPS73501 for VDDA2P5 and TPS74701 for VDDA1V0. (Both are 500mA LDO).

Pls advise can we use 2x TPS73501 or 2x TPS74701 for better BOM control? Any particular reason to use different part number for these two rails?

From the power consumption data of the document, It show that the maximum current (base on 1000Mbps) consumption for the 2.5V is about 135mA and VDD1P1 is about 107mA. Can we use 300mA LDO for both rails instead?

Look forward to your comments and thanks in advance.

Thanks and regards,
