Siglent SPD3033X-E component ID
« on: November 05, 2022, 02:20:56 pm »
I am repairing a Siglent SPD3033X-E power supply.  There is a short somewhere dragging down a 78L05 regulator and another component that I can't identify is getting hot.  The unidentified parts is an SOT223 package with marking 81Y6 and N05A shown in the photo.  The silkscreen identifies it as U2, it's an IC.  I suspect it is some kind of regulator.  Anybody know a part number for this?

A schematic would be a big help.   :horse:

I figured it out.  It's an LM1117MP-3.3.
