something about TLV431A

Other Parts Discussed in Thread: TLV431A


I have something wrong with TLV431A;

I use it as the reference voltage IC to  a DDR IC, and have a filter capacitor of  0,1uF/16V 0402 between GND and pin 1(REF), our package is SOT-23-3

In that case ,there is a  big ripple voltage about 370mv ,

and then I delete that capcaitor ,the ripple voltage disappered .

I'm wondering why,Please help me ,thanks.

I wish you could give me some literature,thank you very much.
