I was picking a 5V high-performance LDO for RF mixer, and found that the parameters of LDL212 are very similar to those of the LDL1117 two series, the specific models are LDL212PU50R and LDL1117S50R, I checked their PSRR and output noise is almost the same, except for the obvious difference in the packaging between the two, I didn't find any major performance differences.
For the power supply of the mixer, to get better performance, how do I choose these two models? Why?
