OVERCURRENT PROTECTION WITH MOSFETS SCHEMATIC CIRCUIT DIAGRAM

In many applications that require a power supply of several amps or less a linear voltage regulator with 3 inputs, such as the LM317 , is used. They are easy to use and inexpensive. In addition, with the addition of several electronic elements added to the front of these elements, the overcurrent protection is limited to provide the necessary protection. This current limiter prevents the regulator from being damaged by keeping the maximum output current Imax at a constant level.

When an error occurs, the power to the transition transistor is approximately equal to the VIN x IMAX. In the design of a regulator that can operate under an overload, if a fault occurs in the feedback floor, an overloaded part is required.
