rosscopicotrain:
The part number is LP2950 3.3v in a TO-92 package.
Page 1 of the datasheet shows a "simplified schematic" with a 1uF on the input and a 2.2uF on the output.
I'm not sure what is meant by a "simplified schematic"...
Simplified schematic is a block diagram of the chip internals which doesn't leak too
much intellectual property, I think they meant "typical application" for that diagram.
Shows even TI engineers can be a bit crap sometimes, or perhaps when the datasheet
was converted from NatSemi to TI format it got a bit mangled. (That's got to be a
mind-numbing job thinking about it)
