a regulator.

A linear regulator works kinda like an automatically adjusted resistor that
changes value according to the current draw you have, giving you the target
voltage under whatever the load conditions are.
LM7812 would do exactly what you want.

Or get a switchmode DC-DC converter regulator... that will waste much less
power.  there's ones you can get that are prebuilt for general use, and even
fit the basic footprint of a linear regulator... I forget what ones I've
used before, but a quick websearch popped up this one.
