What is the output current during Disable mode? I am looking in REG102(NA-3.3V) LDO Regulator. Where I can find details?

I'm not sure that I understand your question. When the part is disabled per the EN pin, it is off and passes no current from Vin to Vout.

Please read the ground rules post at the top of this forum and always remember to begin the title of the post with the part number and to put the part number in the tags.

For example, in TPS60151 there is a detail about the output current during shut down when ENABLE pin = 0V (Isd = 10uA). Why there is no such detail for REG102?

The 10uA spec for the TPS60151 is shutdown current. This is the current drawn by the IC when EN is low. The corresponding spec for the Reg102 is ground pin current. It is specified as 0.2uA max.

Thank you. In addition, what is the current consumption on the REG102 when there is no load at the output?

This would be the ground pin current which is also specified as well as having a graph further down in the datasheet.
