LIS2DE accelerometer drawing huge current - Power down mode not working

Hi,  I am working on a custom board wherein, I am using  LIS2DE12  accelerometer. The custom board draws around 0.1mA current. After the removal of the accelerometer from the board, the board drwas only 3uA current. So, I  would like to disable the accelerometer operation for minimising the current consumption, and for this, after initialization, I am writing the power down command 0x00 to the register CTRL_REG1 (20h). But the accelerometer still draws 0.1-0.2mA current. Please suggest the possible reasons for the same.   

 

Thanks
