Use a 6V transformer. Use an LM317 regulator and adjust the output voltage to 3V.

Click to expand... You can use voltage regulator for 3,3V and one shottky diode (2-3A) which will lower 0,2-0,3V and you will get around 3V on output. Input voltage can be 5V if you use LDO regulator. or You can use something like this : http://circuits.radio-electronics.co/power-circuits/12v-to-3v-convertor/
