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 ...

The LM317 regulator melds with HC4053 CMOS switch to make a 16-W PWM power DAC, charting a less traveled by path to power.

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four di… ...

But isn't the LM317 regulator taking care of that itself already? Is it safe for powering a laser diode?
