Using the LM317 in this configuration causes it to behave similarly to a Zener diode with a dynamic internal resistance of approximately 1Ω or less. This dynamic internal resistance will provide a ...

As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. ... to a large area of copper on the PCB if you can, ...

Instead of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power. It integrates an LM317 positive regulator with a ...

A common use for LM317 configured as a current source is as a high impedance load for a power MOSFET source follower. Every DIY audiophile has stumbled across this as the output stage of a ...

See this diagram,I've been told the the proprietary drivers offer some extra protection from very short spikes (on power up and shutdown) in the current which laser diodes are very sensitive to ...
