Is that the end of the story? Archived from the original PDF on 18 April The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.

How the adjustment pin is connected determines the output voltage as datashheet.

National Semiconductor

The LM negative complement to the LM regulates voltages below, rather than above, the reference. Understanding the Details of Fuse Operation and Implementation This article provides an overview of some subtle yet important aspects of fuse functionality and design.

Just in case I was asked I’ve been back searching for where I saw the info. Yes, my password is: 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.

Ok I think I follow you drift. Sep 7, 2, So while this is comfortably above the typical minimum load current of 3. The output voltage formula is So it the choice of R1 will depend upon the desired output and the choice of R2 and the need to keep a minimum of say 10mA ml117. Nov 23, 8, 6, The output current is that l1m17 from dropping the reference voltage across the resistor.

LM datasheet..R1,= or ohms ?? | All About Circuits

Aug 20, 8. I am searching on information on building a 10 amp battery charger. So it is a design decision that should be made in view of the application at hand. The LM is a ddatasheet adjustable positive linear voltage regulator. I won’t quote the whole reply. Aug 20, 5. It was designed by Robert “Bob” Pease. And the biggest why is why all the manufacturers data sheets show in their typical application notes and don’t make the proviso that you have?

Archived from the original PDF on 31 March Aug 20, 4. In other projects Wikimedia Commons.

The LM relates in the same way to the fixed 79xx regulators. Aug 20, 9. The LM needs 10 mA holding current and corresponds to ohms at 1. Aug 20, 2.

Jan 16, 29 0. This page was last edited on 6 Julyat The minimum load then includes an actual load? Wikimedia Commons has media related to LM and Voltage regulator circuits.


Sorry that’s a lot of questions but let’s get right l,117 the bottom of this. If the adjustment pin is connected to ground the output pin delivers a regulated voltage of 1. Aug 20, 3. However when I happened upon the Wikepedia page for LM I see datasheets from dtaasheet manufacturers all of whom show ohms in their LM datasheets.

Because of this, the error term in the datasneet cannot be ignored and the value of the low-side resistor becomes more critical. How Does a Fuse Work? So where is the thing coming from? I think I now understand the LM as well as I ever will. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. The alternative is to use a switching voltage regulator which is usually more efficient but has a larger footprint and requires a larger number of associated components.

Jan 25, I’d like to know WHY you choose a when, if I understand properly, you want to make a Battery charger of up to 10A. This includes Texas Instruments. Mar 31, 23, 7, Since the voltage across this resistor datassheet 1.

Linear integrated circuits Voltage regulation. Here is the Fairchild datasheet for the LM Aug 20, 1. Aug 20,
