- 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?
- Creating a high current LM317 regulator | All About Circuits
If the goal is to use a NPN for the bypass transistor, then turn the regulator upside down by using the negative complement to the LM317 called the LM337 The Bowden circuit requires a more positive input to the LM317 that you do not have Here is the general idea of how to use the negative regulator with an NPN current-booster

The attached file, LM317 zip, contains: LM317 sub - place in \SwitcherCad\lib\sub LM317 sym - place in \SwitcherCad\lib\sym\PowerProducts That way it will show up in the list with Linear Technology's power products Since I've added LM317 sub in the symbol itself, you don't have to use the INCLUDE LM317 sub SPICE directive
- LM317 as a current limiter control | All About Circuits
I'm sorry, I guess that I wasn't clear enough I don't need it as a Li Ion battery charger, I want to add a current limit circuit in order to make a lab power supply my intention was to use a LM317 as a voltage regulator that will provide 0 to 30V and then to add current limit circuit - seems one like "crutschow" suggested, but with an additional power transistor, so that it will be able to

- LM317 Voltage Drop (IN gt;Out) Vs Efficiency | All About Circuits
The LM317 I noticed got very warm, but not overly hot I decided on the LM317 to regulate, because the source voltage can be from about 14 x volts when the alternator is running, or down to (say) 11 8 volts if the battery bank becomes depleted Also I wanted enough head room voltage so that the LM317 would provide the constant 6 4 volts
- LM317T Is there a minimum voltage inputtoget the required output . . .
Is there a Voltage drop when making a voltage regulator when using the LM317T I am trying to regulate the voltage onto a small load to 12 Volts I have a battery with a voltage of 13 8 volts as the supply but the output never can be set at 12 Volts I an trying to understand why
- LM317 - LM338, big voltage drop under load | All About Circuits
LM317 and LM338 are easy to use and pretty straightforward devices for voltage regulation LM338 is said to be able to supply 5A and LM317 more than 1A current Just as an experiment I built two regulators, one with 317 and the other with 338 I used 220 ohms 680 ohms which gave me an output voltage of about 5 8 Volts So far so good
