Nothing wrong with the LM317. The capacitor on the output pin, blocks all of the 'noise'.

I already know all about matching to output capacitor -esr
And selecting capacitor Cadj in the lm317

I Want recommendation
Regulator in the same configuration of LM317
Regardless of price that better

I'm probably going to change the regulator lm317
to
LM1085

For my project on the ARCAM FMJ PRE

To create a voltage of 5 volts positive
I need resistors
121Ohm
And
365Ohm

Currently in the ARCAM PRE
the smd resistor ar
470 OHM resistor ( R1)
1220 ohm and 220 ohm (R2)


So my plan
Replace the (R1) to 121 ohm
and
(R2) to 121ohm+243 ohm

the output capacitor and the adjast pin cap i chenge to 22uf

KEMET - T356K226K035AT - CAP, TANT, 22UF, 35V, RAD

and the input smd 100nf capacitor
i change to 10 uf rubycon ZLH CAP

I think LT3080 is better if you don't need 7.5 A
