Hep identify this SMD

[Speedy78]

So long story short I washed a really sweet flashlight one too many times and it stopped worked. I originally thought water damage but if I tapped the light I got flashes from the LED which indicated to me a short somewhere. Upon opening her up I discovered the LED positive had snapped off the PCB (probably from all the banging in the wash). To re-solder this I had to pull out the guts. After heating up the epoxy I began to pry it what I thought was a clear spot on the board. In reality I shattered this little guy. It needs to be replaced and I have no idea what it is.

Position looks to be U3 on this board and it has what looks like 3036 written on it. 3 Contact points on the lower side and two up top. I need to know the name and package size so I can order one and see if I can resurrect this light. It is maybe 3mm from end to end and about half that in width.

Picture left large intentionally.

Note sure what it is, but the package size is a SOT-23-5

 

[crazyspaz]

my guess

 

[ARG]

That's a SOT-23-6 though

[Dr_Evil]

my guess

I think that might be it with one middle "pin" removed.

 

[ARG]

But then either the GND or Vout pin has been removed which doesn't work

Got any pics from the other angle speedy? Is it a SOT-23-6 with a pin clipped?

 

[Speedy78]

There does not appear to be any clipped pins. The other side has a small ridge in between the two pins that just looks like where the two sides were bound together.

When in doubt, just say it's a mosfet.

The fact that the silkscreen had a U identifier says that it is a microchip of some kind, probably a linear regulator. Transistors generally use Q as an identifier.

If you can draw up a schematic by following the traces (huge pain in the ass) then we could probably work out what it was.

Many SMD devices clip the middle pin and use the mounting Tab as the connection, this wasn't done here but a replacement part could have that Pinout.

Hmmm...I don't know much about SMD stuff and I never can figure out package types even when I have the data sheet, but is there any chance this is what you are looking for?
