Jan 5, 2025 · I've seen the circuit diagram (found on the web) part of a Li Ion battery charger attached and from what I understand, the second LM317 (CC) serves a current limiter. I would like to ask for …

Mar 30, 2025 · The circuit in the picture with LM317 should provide 1A current, but it gives only 266 mA. What am I doing wrong? I have also attached LM317.asy and LM317.sub downloaded from the link. …

Nov 30, 2024 · I would like to add to this basic LM317 based power regulator circuit of a variable current limiter (0 - 3A), preferably with a led indicator. appreciate your suggestions/comments.

May 29, 2025 · Hi, I'm new to LTSPICE. I added LM317 component .sub and .asy file to the library but i still cant find it when i open my LTSPICE. May i know what's the problem? Attached is the LM317 file …

Apr 8, 2010 · Here is the Spice model I used for the LM317. Code: *LM317 TI voltage regulator - pin order: In, Adj, Out *TI adjustable voltage regulator pkg:TO-3 .SUBCKT LM317 1 2 ...

Mar 8, 2025 · The LM317 has about a 1.5V dropout voltage, so 3.3V input may not have enough headroom for the load. I'm not sure that the line transient response of the LM317 is going to allow …

Nov 19, 2024 · The charging mechanism should be CC then CV during the end of the charging. I'm using LM317 component to achieve constant current source circuit. TL431A acts a temperature …

Oct 6, 2019 · Below is an LTspice simulation of an LM317 constant-current circuit with a 5Ω fixed resistor in series with a 100Ω pot. It shows the current for the pot adjusted from 0% (12mA) to 100% …

Dec 8, 2016 · Hey guys! Any of you knows where can i find the LM317 ADJUSTABLE Voltage Regulator for multisim? It would be very appreciated.

Feb 25, 2015 · To keep the voltage from rising above 13.8 volts I used an LM317 regulator circuit. I found the circuit design on a renewable energy web site in the U.K. This is the circuit that I used. It …
