Using a depletion mode mosfet as a current limiting device
I have recently discovered the exciting world of depletion mode mosfets. Curiously, even in this document, I found nowhere that a depletion mode mosfet could be used as a current limiting/inrush ...

Designing a current limiting circuit for my project
I've got a small DC brushless motor for which I would like to set a current limiting circuit as a protection against over-current.
I thought I could pull it off with a simple fuse (or those current ...

Current limit to 500mA (maximum) at 12V
I have a 12V DC output which can output 1A (maximum.)
I want a circuit that limits the current to maximum 500mA, so I don't accidentally draw more than 500mA as that would probably mean I have shorted ...

Parallel current limiters, ballast resistors and transistor matching
Are ballast resistors (R17, R8 and R5) required when using parallel current limiters as show below?
I found it hard to find working examples on the internet with values already present to tweek ...
