Low noise regulator for DAC & clock

[roderickvd]

In 2022 TI released the TPS7A94: https://www.ti.com/product/TPS7A94

Interesting part, no? Compared to an LT3045 it has lower RMS noise, lower voltage dropout and twice the maximum current. It seems to recover faster from transients too. LT3045 continues to have the higher PSRR over most of the range (the entire range?).

only 5,7v input ...not frendly usable. Noise is not major goal for good design, maybe for power supply for RPI. Package not diy frendly.

TPS7A94 has unfortunately quite high LF noise (2-3x LT3045). RMS noise it not very important. Besides TPS7A94 is max 5.5V part.
