Voltage Drop Help

9 Volts is low. The fact that it's short duration doesn't matter.

At any rate, a regulator may work. You'll just have to make sure it's rated to supply the controller.

A conventional linear regulator can only regulate to a voltage higher than its input so it won’t help here imho. A filter with some significant bulk storage capacitance should help.

I'll admit these electrical parts are much smaller than I work with normally, so I'm outside my realm of expertise. That said, I know Pololu makes some step-up/step-down regulators specifically for battery powered applications where the voltage starts above the regulated voltage and ends below it. I have no idea what sort of power levels we're talking about here for the controller, though.

That is a switching (as opposed to a linear) regulator and a pretty extreme fix for a glitch imho. A decent filter should suffice.
