multiple output

Voltage regulators in parallel

Hi guys, i'm planning to make a robot which requires 12V,5V and 3.3V power lines regulated from a approx. 15V battery.Would it work if i used 3 voltage regulators(one from 15 to 12V,one from 15 to 5V and another one from 15 to 3.3V) connected in parallel? Or is there another way of getting 3 different regulated voltages from one power source (the 15V battery) thanks.
