The following precautions should be taken in the application of 7805 three terminal voltage stabilizing IC in circuits:
The input and output pressure difference should not be too large, as it will rapidly reduce the conversion efficiency and be prone to breakdown and damage. The maximum input voltage cannot exceed 35 volts; The output current should not be too large, and 1.5A is its limit value. For high current output, the size of the heat sink should be large enough, otherwise it may cause high-temperature protection or thermal breakdown; The input and output pressure difference should not be too small, as the efficiency of voltage stabilization drops rapidly below 2 volts.
