Nov 20, 2025 · The LM317 in normal regulator operation, is designed to maintain the Out pin voltage at a value of Vref (1.25V) greater than the ADJ pin voltage, no matter the external …

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 …

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 …

Jan 17, 2009 · Hi Rardi, Sadly, the LM317 is not very energy efficient. It makes for a very simple solution for linear current or voltage regulators, but it is actually very wasteful in terms of power …

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 …

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 ...

Feb 17, 2020 · The LM317 can go to a junction temperature of over 100°C without failure. If it gets too hot it will automatically reduce the current to limit any further heat build-up.

Mar 1, 2023 · A LM317 circuit controlling to 20mA My concern with this however was whether any damage could be caused to the analog output device in the rig controller, since it will …

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.

Jul 9, 2021 · The only reason I'm a little concerned about this is that the recommended input and output capacitor values for the LM1117 (in the voltage-regulator circuit examples) are much, …
