LT3045 PSRR vs voltage drop

Dear Support,

is it known how PSRR of LT3045 depends on difference VIN-VOUT?
I plan to use it to produce voltage a bit below 3.0V from 3.3V rail. The datasheet specifies max. dropout voltage as 350mV, so theoretically 2.94V should be already correctly regulated. Can I expect high PSRR performance then? Would it get significantly better with output regulated to 2.9V or 2.87V?

Best regards,
