Default Very Low Noise 5V Jung Reg

For those not happy with the AD817, try the AD8651 opamp. Estimated 0.5 uV rms noisr 1 MHz bandwidth powering a Tent Clock using extra local decoupling!

Nothing wrong over 400MHz bandwidth on a scope.

Hi FMAK,

Are you sure about the Part #, the AD8651 is a CMOS part with a 5.5V max PSU, and is more noisy then say a 5534

Read the data; 2.7 V; fine on 5V single rail.

Much faster than 5534; quieter than the AD817.

Yes, I am sure, I have done the two meausrements. Does the 5534 work at 5V' don't htink so. I am referring to the ALW implementation which powers the opamp from the output.
