Short circuit & current limiter using MOSFET<\/h1>\n

To protect the power supply feeding your electronic equipment it is more than useful to insert a limiting current and short-circuit protection in this line.\"\"<\/p>\n

The circuit described is very reliable and easy to adapt to your needs, in this case it feeds an external RF preamplifier with 0,318A limited current.<\/p>\n

The only thing to take care about is the value of R1 (the limiting current sensor) in the schematics below.<\/p>\n

How to limit current<\/strong>?<\/strong><\/p>\n

We know that a PNP silicium transistor conducts when the voltage emitter-base is greater than ~0,7V D.C.If we look to the schematic R1 value is 2,2\u03a9.<\/p>\n
