Modern replacement to Regulator LM317 With low noise ?

Modern replacement
to Regulator LM317-T With low noise ?

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 would say the LT1085.

Hi, LT1086CT is allegedly better, rds, sreten.

Thank dear brother 🙂

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

me too.
my choice is LT1085

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