I'm looking for an adjustable or fixed 6V regulator, performing up to 6A peak current. The continuous consumption will be much smaller. It needs to be a LDO regulator, since I will be powering the regulator from a 2S LiPo batery (7.4V nominal). The drop-out would need to be about 1V or so.
Could I use a switching regulator for this kind of thing? I'm afraid of noise on the power rail that would be bad for the motors and would make it harder to control them. They will be used on a robot for robocup rescue B. I'm using a 9.7:1 Metal Gearmotor motor with a DRV8432 motor driver.
I will be driving 4 motors, so I'll probably get a separate regulator for each one.
