Voltage regulator. 7803 is what you want methinks.

There is lots of 3.3 Volt regulators out there, what sort of current are your looking for ?? Or are you just wanting 3 volts to run a couple of LED ??

assuming its dc, you could use a voltage divider circuit (resistors). or maybe even a voltage regulator, but that would involve more components.
