Default Linear vs. Switching 24VDC Power Supply for Mic Pre

If I have a 24 Volts DC
regulated stabilized output low
ripple but switching power supply

Can I use that for a microphone
preamplifier module which
requires 24VDC for operation?

Or must it be linear or I will
damage the unit?

Yes. It will work.

No and no.

Depending how well the mic pre was designed it may or may not benefit more or
less from a linear supply with even lower output noise. You omitted to mention
the actuall ripple and noise voltage ( and measuring bandwidth ) from the
switcher.

Try it. Just make sure that you're not blasting a 40KHz signal through
your system before you crank up the volume.

It's an order of magnitude
greater but still low?
the switching is 0.1% vs 0.01%
but that's still low anyway

Probably little chance of "damage".
However "low ripple" depends on the context.
It is night-and-day different if you are talking about
a battery charger vs. a supply for a delicate circuit
like a mic preamp.

Beware of power supply noise getting into the preamp
circuit. Particularly a problem if it is supersonic where
you may not immediately see the adverse effects. Do you
have an oscilloscope available?

The linear supplies I design have ~ 500uV of noise ( you can't really see any ripple
) in the audio band. How does that compare ?

yours are superior do you sell
them, if the noise floor is
unbearable I am thinking of
'switching'

no but it was the only one I
could find it was for laptops
but Eeyore ig going to sell me
one I think

These are power supplies that I design to go into pro-audio gear. Not even high end stuff
actually, just well-engineered. You can do the same with any of the usual integrated
regulators around using carful pcb layout in particular.
