I'm using the LMZ22008, LMZ22010 and LMZ22003 in my design. I need to know what the output impedance for these devices to properly calculate my FPGA supply cap decoupling values...

Hi Dan,
I will reference from
Power Delivery Network (PDN) Tool User Guide
The LMZ22008, LMZ22010 have the following values for Rvrm and Lvrm.
Rvrm = 7mOhms (typ)
LVrm = 2.2uH
The LMZ22003 has the following values for Rvrm and Lvrm.
Rvrm = 30mOhms (typ)
Lvrm = 3.3uH
THe Lvrm values are listed in the datasheets and can be found in the block diagram.
