There were chips, but now obsolete as most use a smps circuits.
you can try this kmitl.ac.th/~kswichit/MAX232/MAX232.htm
it has -10 and +10 that can power low-power cmos opamps and chips.
or use national.com/pf/LM/LM7912.html and fairchildsemi.com/pf/LM/LM7812.html
you will need two chips, there was a LM326 but not now.
See orca.st.usm.edu/~jmneal/dual_psu/

see a dual power supply circuit using LM326
