AD8054 Voltage Stabiliser application

Hi,

 

I have a customer using the AD8054 in a voltage stabiliser application.  It is configured as a voltage follower :-

 

0-5V on the +ve pin.  -ve pin connected to the output.  On the output he has two series resistors 5Kohm and 10Kohm to get 3.3V at the divider.

 

He is seeing a wide variation on the output voltage of the Op Amp with some devices outputting 4.39V.  Other devices, deemed "good" see 4.98V.

 

Is this variation at the output of the OpAmp normal ?

 

Any comments/suggestions welcome.

Thanks

Andy
