Welcome to AAC.

Without context—what this IC is in, what the circuit might be—it is a guessing game. Unfortunately, your isolated photo is nearly useless. It does help to see what the package is and that eliminates any normal Rohm part that might be marked TS. They have one part: IMH10A (2SC5437EB), but it is in an SOT-163 package because is a dual transistor.

Can you tell us what this is in? Provide a photo with the surrounding components?
