What is the preferred method for terminating the LDOs if not used? Connect the inputs to VDD or GND (with EN tied low)?

Thanks,

Any feedback on best practice here? If the LDO inputs are tied to GND that seems like it would reduce power by 1uA (max) x 2 (LDOs). I see no other issues. Please correct as needed.
Thanks,
Dan

The best way is tie VIN and EN to GND
