Default Regulators in Parallel

Is it possible to use regulators in parallel
to increase output current ?

or will this not work?

I dun think that will work...coz one regulator will tend to take all the current...and just shut itself down...letting the other take over...and then shutting it down as well...

you'll have to place a small resistor (0.1 to 2R) between each IC's output and the global output

So this will WORK

Will I still get 12V output?

Possibily...you might want to try tweaking the resistor value to get faster better response...I would try 1ohm first...

By the way...that theory by Albert on relativity was pretty cool....

Heeej Marvellous,

make sure (if you're going to use 1 Ohm resistors, which i DON'T recommend) that these resistors can dissipate enough...

Grtz, Joris

I would definetly reccomend a pass transistor if he wants BIG currents...

You MUST use that series resistor or you'll see your 7812's burn one by one, but I would use something between 0.1 and 0.2 Ohm, that should do the job.

Grtz, joris
