The humble LM317 adjustable voltage regulator is everywhere ... including driving LEDs and laser diodes. While this circuit may not be as efficient as an LED driver module or a switching solution ...

LM317 is an adjustable voltage regulator which takes an input voltage of 3 - 40V DC and ... So this is how we calculate the R2 and output voltage for LM317 voltage regulator circuit. This LM317 ...

It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which ...

what is the problem is there. please suggest any idea to get output with out voltage drop. my design with lm317 is must. i can't change another regulator for my module you want short-circuit the ...

If possible please provide the curve of Dropout Voltage vs load current, I apologize for the delay in response with the US Holiday. I took the dropout curve from the LM3480 datasheet by mistake as you ...

The above schematic comprises almost anything you can put around the ubiquitous LM317 positive 3-pin regulator (LM337 for negative voltages, 117 and 137 military versions). The basic circuit dispenses ...
