You can't read the datasheet and make a simple Ohm's Law calculation?bananasiong said:how to calculate that? what is the output if 15V is supplied?
The output will go to 12.5V with a 15V supply and 200mA of load. Therefore the total load resistance = 12.5V/200mA= 62.5 ohms. If the wire's resistance is 0.5 ohms then a 62 ohm resistor could be used in series with it. The power rating of the resistor should be 2.5W.
A 2.5W resistor will get hot but still survive. A small resistor will burn out. Extremely thin wire will burn out.f i drive it in maximum (200mA), like what u have mentioned, the high power will cause heat. will it burn the resistor or wire?
