If you read and understood my previous post you would know the answer to your questions.One thing . . about LM 317T
How am I going to get to know that for what input I give to this IC, am going to have what value of output?
As in what I did practically was I connected LM317T IC and gave it an input of 52.4V DC , at its output terminal I obtained 51.9V DC .. . this was what i measured with the help of DMM
So how am I going to know these values from the datasheet? that for which value of input am i going to obtain that particular range of output? Please help me out here so that I may get to start to know how to actually use this IC and know which one is of my use
