How much current do you require? What's the circuit for, can you use a switching regulator?
Thanks

For up to 350mA the LTC1945 is suited.Or Google "Dual DC/DC Converter with Positive and Negative Outputs".

There are many app notes that show how to add a winding to the inductor in a buck regulator to give a second output that can bee either positive or negative.
