ADP7159-Output and Input Voltage & PSRR

Hi ADI Team,

I am going to use ADP7159 for generating 1.9V (Vout) from 2.4V (Vin).

1. As per Table 9 and Table 10, ADP7159-02 to be used for 1.9V Vout with >2.8V Vin for Better PSRR Performance.

But I could not give < 2.8V input due to thermal performance limitations.

Please provide the PSRR performance which is degraded by 2.4V input for generating 1.9V Output

2. I referred the the conversation in the below link regarding AD7159 Voltage specification.

Link:  https://ez.analog.com/power/f/q-a/53145/adp7159acpz-02-r7-and-adp7159acpz-03-r7-input-voltage-ranges/177053

As per the conversation ADP7159-01 to be used for 2.4V to 1.9V conversion with less degradation in PSRR.

But as per the Ordering Guide of Datasheet, ADP7159-01 model will support upto 1.8V output.

Kindly clarify this doubt. Which LDO model to be used for better PSRR performance with 2.4V Vin &1.96V Vout?]

Thanks in advance,
