Hi Ogane-san,
How much difference is observed between the two devices?
There are several possibilities. The most probable are:
The current regulation varies from device to device. This variation can be due to the VREF voltage variance or the internal comparator.
The internal oscillator varies from device to device. A slower internal oscillator can cause more current ripple reducing the supply current.
