REF2125: REF2125 use Vref voltage for sequencer UCD90320

Hi.

I want to use a reference voltage REF2125 for the chip UCD90320.

I use REF2125 with the following connection parameters: Cin = 4,7uF, Ccs = 100nF, Rcs=330 Ом, Cout 4,7uF. At source (REF2125) out voltage = 1.9V, but should be 2,5V.

I can something that is not connected correctly?
