REF6225: REF6225 Reference Voltage

Part Number:REF6225

Hello,

At this time, I'am work with a REF6225 voltage reference. Through the analysis of the data sheet, I'am saw that it would be necessary to use a capacitor with a series resistor at the output of the REF6225.
In this way, some doubts arose:
What type of capacitor (tantalum or ceramic) makes the circuit more efficient?
If I use tantalum capacitor, the value of the ESR resistor is not the same as the ESR value of the tantalum capacitor?

I attach the schematic of my circuit.

Thank you.
