I want to build a simple driver for a LED light.
It is 3watts.. and runs around 3.3v so thats about 990ma
I want to know if I require the Voltage set before entering the LM317 to regulate the 900ma Current.
Or the LM317 can be configured by using 2 resistors, 1st @ the adjust pin and 2nd at the output pin!
that way Resistor 1 Sets Voltage to 3.3v, Resistor 2 Sets 900mA
anyone please confirm this for me..
