How Does a Fuse Work? Oct 29, 7, 3, I won’t quote the whole reply. Ok I think I follow you drift. By using this site, you agree to the Terms of Use and Privacy Policy. So while this is comfortably above the typical minimum load current of 3.

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

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 flowing. 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. Why is it that I’ve yet to find a LM circuit on the dataasheet that uses ohms?

I think I now understand the LM as datasheeet as I ever will. However, the 78xx device’s quiescent current is substantially higher and less stable.

SCR datasheet or equivalant Posted by enduroz in forum: Aug 20, 9. Failure to do this may cause the circuit to short.

Since the voltage across this resistor is 1. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. As for the adjustment pin current of 0.

Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output. Jan 25, It was designed by Robert “Bob” Pease. Here’s a target that reacts when it’s hit by a laser beam. Do you already have an satasheet The LM relates in the same way to the fixed 79xx regulators. The device can be configured to regulate the current to a load, rather than the voltage, by replacing the low-side resistor of the divider with the load itself.

Mar 31, 23, 7, I am searching on information on building a 10 amp battery charger. Just in case I was asked I’ve been back searching for where I saw the info. Aug 20, 5.

Nov 23, 8, 6, Retrieved from ” https: This includes Texas Instruments. The LM is an adjustable analogue to the popular 78xx fixed regulators. You May Also Like: For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. Aug 20, 2. Aug 20, 3. Now let’s consider a few other things that might influence the choice we actually make. Nov 9, 5, The LM has three pins: From Wikipedia, the free encyclopedia.
