With supply chains breaking due to the pandemic, some resources are becoming hard to procure. There are cases when someone’s profession or life, depends on these resources. Being a technical author ...

However, fixed resistors resulted in application inflexibility that precluded use at lower voltage and different types of batteries. In the updated circuit, all thresholds are set via potentiometers, ...

This can useful for a number of applications including driving LEDs and laser diodes. While this circuit may not be as efficient as an LED driver module or a switching solution the LM317 is cheap ...

(This is a GOOD standard application shown in every LM317 data sheet ... So it's not a bad circuit. This is a useful trick, especially if you have a load that's floating, and isn't grounded ...

When prototyping a new circuit, often the goal is to get a proof ... and for smaller projects we might just reach for an adjustable LM317 voltage regulator to dial in the correct voltage and ...
