Hello, I'm trying to identify and get the datasheet for this linear voltage regulator. I don't recognize the logo, and haven't been able to match it in the usual places online. Google and other sites have not helped me with the component marking "A2NK". It appears to be an SOT-23-5/SOT-25 package or similar, output and input at top left and bottom left respectively in the attached (enhanced) photo. This is the only part on the board with any logo, and an other-than-generic part number.

From a reply given on another forum, I have "IK Semicon" of Korea as a possible manufacturer of this chip.

Scotophor,

Thanks for coming back with the answer. Too often new people on forums will figure out their problem themselves or get the answer elsewhere, and just disappear. I, and probable others, appreciate your return to share the solution.

Well, I haven't quite got "the answer" (datasheet) yet, but I fully intend to post here when I do, if it comes from another source.

So far, IK Semicon has not responded to my email.
