I need a 3V ( 2 1.5V batteries) for a RC car transmitter and I have a Raspberry Pi Model B giving out 3.3V. How can I convert the 3.3V from Raspberry Pi to use it in my RC car Transmitter ?
Basically I'm trying to run the RC car with the Raspberry Pi GPIO pins 1, 3V3OUT, and Pin 39 GND.

I think the additional 0.3V won't bite.
Should you really be concerned about this you can get a Schottky rectifier like
1N5819
to drop the voltage by 0.2V.By the way
1N5819
are so cheap that you can get boxes of thousand for a few bucks - you can get a few hundred of those and start replacing1N4001
's in your circuits with those, and in some circuitry its lower forward drop means better efficiency.
