Part Number:INA240
Hi
I'm encountering some issues
I'm wondering how much current INA240A2PWR consumes when it is used in a 12V motor current detection application.
Because the 3.3V LDO kept on burned down due to the possibility exceeding the power dissipation with SOT23-5 package (due to space limitation)
Sometimes I'm seeing around 25mA being drawn on the 3.3V while the other component only consumes 3mA. (There are only 2, INA240A2PWR and a MCU.)
So I'd like to understand how much current INA240A2PWR may consumes. Datasheet says it is 2.4mA quiescent. But will it be more like what I've observed?
