I want to put the arduino one burns?
I also need to volage regulator 3.3v output 3.2 A
QuoteI want to put the arduino one burns?What?QuoteI also need to volage regulator 3.3v output 3.2 ATry this:-http://uk.farnell.com/diodes-inc/ap1084d33g-13/ic-ldo-reg-3-3v-3to252/dp/1825261But dropping down from 11V will dissipate close to 25W so you would be better off with a switching regulator or DC to DC converter. It needs to be at least 15W so it could be pricy.http://uk.farnell.com/murata-power-solutions/lsm-3-3-10-d5-c/dc-dc-conv-non-iso-pol-1-o-p-33w/dp/1577218
Let's not make fun of people for whom English is a 2nd language.I'd not want to use a linear regulator to take 11.1V down to 3.3V. 2/3 of the power will be wasted as heat.Why do you need 100A? Do you understand that just because a battery is capable of a lot of current, current is controlled by the load.Now - do you really need 3.2A at 3.3V?
That chip runs from a -minimum- of 3.3V, up to 5.5V. In fact, it seems to be rated for only 20mA @ 3.3V, and still only 30mA @ 5V. So you can't get 60mA per LED from this chip. 30ma x 54 = 1.62ASo you really need 5V to get the maximum current of 30mA per LED. I'd get a step down switch mode power supply SMPS that can accept a range that includes 11.1V (LiPO do get lower as they discharge) and puts out at least 3A. And still connect the 11.1V to the Arduino's barrel connector.
