This happens if you only copied the schematic file but missed the simulation model ( .MDF ) file. Ensure all files from the download package are placed in the Library folder.
In a real circuit, if you suddenly connect a heavy load (like a motor or high-power LED) to your LM2596, the voltage might dip momentarily before recovering.
By default, Proteus installs libraries here: C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY (For Proteus 9, it is similar but may be under AppData local)
Ready-made packages for TO-263 (surface mount) or TO-220 (through-hole) packages for seamless transition to PCB design. Top Sources to Download the LM2596 Library lm2596 library for proteus top
Copy the .LIB and .IDX files into the library folder of your Proteus installation.
