Power current consumption in low power mode in STM32L0 is higher than as compared to the datasheet values.

Hi,

I am using an STM32L010 and want to operate it in low power mode. The way the firmware works is I start the LPTIM2 with interrupt every 1 second and then go back to sleep once ISR is serviced. Right now the ISR just has a variable that acts a counter and keeps counting down to zero. While the system is in sleep I get a current consumption of 300uA approx according to datasheet it should be 2uA approx. Is this because of LPTIM running in the back ground or should I be seeing a lower current consumption?

Thank you in advance.
