Is my LM1084IS-ADJ a fake or counterfeit device?

Xuanlong Chen

Hi! Recently we encouter a problem that LM1084IS-ADJ failed, and failure analysis suggestted that this lot of devices were fake or counterfeit. The evidence is the marking and die apperances were different, and the logo is different.

We want to know the exact logo rule for LM1084IS-ADJ, and whether they are fake devices.
