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 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 …

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 …

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 …

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 …

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.

Jun 20, 2017 · Hi, I am referring the below circuit diagram to make a High Current Linear Voltage Regulator circuit. This circuit is given in LM317's datasheet. I need...

Feb 8, 2018 · For example, the ubiquitous LM317 is often used to make a simple supply but its minimum output voltage is nominally 1.25V, requiring an added negative voltage to adjust to a …

Jan 10, 2017 · The value of R3 determines the relative division of current between the MOSFET and the LM317. It does regulate the voltage, as shown by the V (out) voltage with change in …

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 …
