Is this possible?

As somebody else mentioned, these types of supplies that guarantee that they can sink (as well as source) are used for mid-supply memory terminations. They're referred to as "VTT" or "termination" supplies.

Here's a table of LT termination switchers. They are overkill.

If you can convince the customer to use a linear (it is fairly low current) then the TI TPS51100 will work. You'll just need to fake a 2V supply because its output is half of the reference supply.
