注意：如果你的系统是64位的，路径可能在 Program Files (x86) 文件夹下。如果找不到该目录，可以在C盘搜索 LIBRARY 文件夹。部分情况下，文件还需放入 C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY ， ProgramData 可能为隐藏文件夹，需要开启“显示隐藏文件”功能。
Restart Proteus to update the component list.
This happens if you only copied the schematic layout visual but omitted the underlying simulation engine data. Ensure that any accompanying files (such as .MDF or SPICE model configurations) are placed inside the Proteus MODELS folder, located right next to the LIBRARY directory.

Connect the pin directly to Ground to keep the regulator active.
The LM2596 is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator.

He attached it to a private message for SparksFly. Then, on a whim, he added his old notes:
| LM2596 Pin | Connect to | |------------|----------------------------------| | 1 (VIN) | +12V (or 7V-40V) | | 2 (OUT) | Inductor (33µH) → 5V output | | 3 (GND) | Ground | | 4 (FB) | Direct to 5V output (for fixed 5V) | | 5 (ON/OFF) | Ground (enable) or +VIN (disable) |

Many libraries simulate the entire physical blue LM2596 buck converter module (including the potentiometer, inductors, and capacitors) rather than just the IC.
While Proteus includes standard voltage regulators like the 7805, advanced switching regulators like the LM2596 require specific SPICE models for accurate simulation and precise PCB footprints for ARES layout design. A dedicated LM2596 Proteus library provides:
