TPS7A8300: Difference between TPS7A8300RGRT and TPS7A8400RGRT

Hi,

We are considering replacing TPS7A8300RGRT with TPS7A8400RGRT.

○ Output current… TPS7A8300 2A [Max], TPS7A84 3A [Max]

I think these two parts are pin compatible, but are they equivalent products with different outputs?
Looking at the data sheet, the internal circuit looks different.

(PSRR Boost is a block only in TPS7A84, etc.)

I would appreciate it if you could tell me what is different, including the characteristics.

Thanks,
