- LM317 current source simulation - All About Circuits
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 How do I add the name "LM317" to the component image?
- LM317 as a current limiter control - All About Circuits
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 an explanation how it's done, since for all I know, the LM317 is a voltage regulator and if it can serve
- LM317 LDO design excercise - All About Circuits
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 configuration Thus for the 1st circuit, this means 1 25V is maintained across the 30Ω resistor, R1, within the limits of the input voltage, the output load, and the minimum voltage drop across the LM317 required for operation
- Combining LM2596 buck converter module with LM317 Linear Regulator
I was thinking along these lines, a small resistor value in series with the LM317 output before the feedback resistor which would need an increase in the necessary buck output voltage Difference the voltage across the resistor with gain, then use a comparator to compare this to a pot wiper
- Adding a variable current limit circuit. | All About Circuits
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

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
- Add LM317 to LTSPICE - All About Circuits
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 i added
- Constant Current Constant Voltage Battery Charger - All About Circuits
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 compensated variable or adjustable Zener diode The input voltage is 12V and my consent is for constant current at 3A, can anyone share with me how to make it constant at 3A
