Sounds nice (except for the BGA part), but is not really /that/ nice. There's the "Vin to Vout Stepdown Ratio" which means that in the default configuration, you need 15V in for 5V out. You can adjust that to "only" 12V in for 5V out, but I guess that this, plus the price (they say $20 in 1k quant) plus the BGA make this not really the big runner. For example automotive applications usually need a lower start voltage. Looks ok for 3V3 out though (starts at 7V in -- and again, you can trim that to get down to 5V in). page 5 for the "Vin to Vout Stepdown Ratio" diagram.
