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 ...

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 ...

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, ...
