TPS7A52-Q1: 0.85V output noise

Part Number: TPS7A52-Q1


The datasheet mentions utilizing a 12.1kohm resistor, as R1 of the voltage divider, to optimize noise and PSRR. To get an 0.85V output and maintain a 5uA resistor divider network, a 10kohm R1 resistor and 160kohm R2 resistor would need to be used. However, that deviates from the 12.1kohm optimization. How much does that affect the output noise? Could that be handled with a feedforward resistor and other noise reduction components?
