LTM4644 & LTM4646 minimum output current


I'm investigating the devices LTM4644 & LTM4646 as a solution to power a Zynq MPSoC device. Thanks to the multiple output capability, it'd be a nice solution.

However, power analysis from tools and datasheets from Xilinx show various current needs (high and low).

For high currents, I plan to combine outputs so this is not a problem.

However, for lower currents, I was wondering about the minimum output current for each ouput. Analysis shows 0.2A need for some voltage (0.9V).

Is there a drawback/limitation to use such power device for such low current consumption? If so, what would be the consequences.
