I'm trying to identify a fault on a printed circuit board in a consumer product. So I tried to find a pin-out diagram, specifications, etc. for this surface mount component designated AA3 03:
There are two of them. I imagine they are ~3V voltage regulators for some small krypton light bulbs wired up in series. But I don't know for sure.
Can anyone definitively identify this component, or cross reference the part number with a more common one; so I can hunt for the specs? Thanks.
