If you want to make the voltages off chip then obviously, you can just use voltage regs.
To create them on chip, you'll need to design such circuits yourself. A quick search on google should give you plenty of schematics, you'll just need to sim them to find out if the'll do what you need.
You'll need to have a very clear idea of the amount of current these will have to supply, and (obviously) design for that.
