It requires external input and output caps.
Ouput voltage is limited to 5.5V.
As already mentioned, the features that offer improved dynamic response and tighter control are of no significance in powering an atomizer.
It's expensive. It lists for over $20 on Mouser.
The Murata OKR-T modules are much better. They are cheaper, smaller, go up to 6V output, and have onboard input/ouput caps.
