Just to let you know: if one day you have to use the LM337 negative voltage regulator, protect everything with TVS or Zeners. This is the most failing component I've ever seen (and I'm not the only one that thinks so, see youtube). I suspect strongly it is very sensitive to ESD. In my last application, after having replaced the LM337 for the 66th time, I protected it heavily and it finally stoped to fry.
