    Hi Vladimir,

    This topside marking refers to the orderable device LM1117IDT-3.3/NOPB.  This device was originally released by National Semiconductor before the acquisition which is why the National Semiconductor logo is on the topside marking instead of a TI Marking.

    You can find our Device Marking in the Package Option Addendum which is appended to the end of the datasheet:

    You can also lookup part markings from the following website:

    Very Respectfully,

    Ryan
