  This is a single voltage regulator (5V) although it comes in several variations for different fixed voltages.
  
  I've not heard of an integrated voltage regulator that has multiple outputs. It wouldn't make sense from a design or marketing perspective.
  
  There are variable voltage regulators and most fixed voltage regulators can also be made to regulate voltages higher than their specified voltage by using a voltage divider as shown on their datasheets. These are still single output regulators.

  Cool thanks I had a feeling that would be the case but it would be really cool if i could make a single chip do what i wanted

  Pat -
  
  There are certainly multi-voltage power supplies that can produce nearly any voltage or set of voltages that you might need, but that's certainly not a "one-chip" solution, as you had hoped for.
  
  Just out of curiosity, what is it that requires 9 volts?
  
  Lastly, what kind of amperage are you going to require, as a voltage regulator may not be the only solution? The lower the current requirement, the better chance of a possible, alternate solution.

  There actually is a single chip solution, the KA7631. Mouser currently has 563 in stock.
