According to datasheets, the LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output voltage range of 1.25 V to 37 V. It requires ...

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… ...

Tying the Adjust terminal to the Output terminal forces the internal regulator to compensate, pushing the internal NPN transistor into saturation. The NPN transistor in saturation has a V CE (sat) ...

July 4, 2015 [Afroman] contacted us to share his new video on the LM317. The humble LM317 adjustable voltage regulator is everywhere. From wifi routers, to high spec lab equipment.
