I may be mistaken, but SC70-5 is much smaller than SOT323 (0.65mm pin
spacing instead of 0.95mm).

Here is the SC70-5 footprint I use for an amplifier (LPV511). If memory
serves, I took it from Philip's (ne NXP) website and it is the wave
solder version (easier to hand solder with the large corner pads).
There is a different (reflow probably) footprint in the LPV511 datasheet
on National's website.
