This audio limiter circuit is easy to build ... Audio limiters can be used in a transmitter schematic or in any circuit you need a constant audio level.

This file type includes high resolution graphics and schematics. Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems.

Figure 3 The active regulator, while not as popular as the capacitance multiplier, it does show up from time to time in published circuits. I first saw this circuit on Charles Wenzel’s website [1].

Therefore, if the current limiter is connected with a +5-V supply, the load will get ~3.4 V, which is unacceptable in low-voltage circuits. 2. This more complicated current limiter has the ...

Honestly, nothing — until you start looking at its thermally compensated current limiting circuit. This one is by [DiodeGoneWild], who you’ve really got to hand it to in terms of both the ...
