The circuit intends to produce an adjustable voltage regulator in the range of 0V to 3V with the use of the three-terminal adjustable regulator LM317. Without applying any methodology, the normal ...

This is an LM317 based adjustable voltage regulator with a maximum output of 3V and 1.5A. The output voltage depends on the VIN, R1 and R2 values, so the circuit can be modified to use with a maximum ...

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 we’re ...

Powering your gadgets generally seems like a necessary evil. To help with this [Felipe La Rotta] made a really nice bench power supply using a PC power supply and a LM317 adjustable voltage regulator.
