LDO Reference Voltage

Hi all -

I am trying to come up with a reference voltage for an LDO test setup. The voltage needs to be able to vary between 2.42 and 2.58V and have low noise specifications of 400nV/√Hz up to 1kHz and 100nV/√Hz between 1kHz and 100kHz.

I have not been able to locate any power supplies or any variable output LDO's with such low noise specifications.

Any suggestions?

Thanks,
TheShoe
 

Re: LDO Reference Voltage

Hello

You will not find any !

All you have to do is to use a REF IC like the REF02 + a buffer with a digital POT on the feedback line :

The REF02 deliver low noise 5V use the digital pot to trim the voltage and the budder to buffer it {in order to deliver some current )

All the best

Bobi
