hello
i have 2.4GHz Video PAL & audio RF modules 16 dB. RX and TX.
need 5V.
how can i supply it?
is it necessary to feed them with a linear supply ? 7805 heats so much.

can we supply it with a switching power supply? (and which is recommended )

thank you.

Why don't use a pass power transistor ?? That transistor will help to the regulator to share current..
