Hi Eric,

For this device, in the datasheet, the quiescent current is the same as the ground pin current. The datasheet also includes two figures on quiescent currents, please see figure 5 and 6.

Hi Jason,

Thanks your information.

As I Know, IGND testing condition is bas on Iout=0mA but LM2941 still have load current, why?

You can access TLV733P spec as below.

Best Regards,

Eric

Hi Eric,

For TLV733p, the ground pin current is tested at Iout = 0mA. But this is the not the definition of the ground pin current. Please see application notes . It has a good explanations on ground pin current on Page 3.
