The power consumption of LIS2MDL in power-down mode

[young]

Hi,everyone.

I measured the power consumption of LIS2MDLTR on the same board in power-down mode.

and found that the LIS2MDL chip on STEVAL-MKI217V1(from mouser) consumes less power than the LIS2MDL purchased separately from mouser.

We have some question and need your help.

1. ​ What is the power consumption LIS2MDL in power-down mode ？ 
2.  Why do the parameter differ between LIS2MDL chip on STEVAL-MKI217V1 and LIS2MDL purchased separately？
