LM317 datasheet..R1,= 120 or 240ohms ??

Yes, my password is: I am searching on information on building a 10 amp battery charger. Aug 20, 7. Jan 24, 1 0. Is that the end of the story?

Ok I think I follow you drift. Quote of the day.

Oct 29, 7, 3, Understanding the Details of Fuse Operation and Implementation This article provides an overview of some subtle yet important aspects of fuse functionality and design. Archived from the original on 17 December No, create an account now. Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output.


Failure to do this may cause the circuit to short.

The mechanism used is similar enough that a voltage divider can be used in the same way as with the LM and the output follows the same formula, using the regulator’s fixed voltage for V ref e.

So while the possible variation in the reference voltage is the more significant of the two, it would be nice to make it truly the dominant error source by reducing the error due to adjustment pin current at least a bit more.

The LM is designed to compensate for these fluctuations internally, making such measures unnecessary. Just in datashheet I was asked I’ve been back searching for where I saw the info. The LM needs 10 mA holding current and corresponds to ohms at 1. Now let’s consider a few other things that might influence the choice we actually make.
