Current Transients -- Choke?


I am modulating power to a pump (power on and off) and when I am doing
this I am seeing dips in the input voltage to my power regulators
(Vin) on other parts of my board.

What is the best approach to guarantee that my Vin won't dip during
these current transients caused by my pump? I added some larger input
and output capacitors that helped a little but didn't fix the
problem. Should I be adding an inductor/choke to help with this? How
should I be calculating what type of inductor to use?

Thanks in advance for any info!
