Hi to all,
I am making a project that requires 2 different voltages. The first to power strings of LEDs needs to be 30v at about 1000mA. The second (the actual control circuit) needs 5v at 200mA.
To make the circuit "bomb proof" I wondered if I should run the 30v supply through an LM7812 or LM7818 first before it reaches the LM7805 that will power the micro etc.
Would this be the best way to avoid stressing the LM7805 or is there a better way?
Thanks Al
PS Eric, my man flu seems to be gone now. Well the missus has got me back on dishes detail so it must have! hehe
