Feedback resistors for adjustable versions (ADJ). Example: 24V to 12V Converter Setup Vin: 24V

Place the Schottky diode between Pin 2 and Ground. Ensure the Anode connects to Ground and the Cathode connects to Pin 2. Crucial: Setting this backward will cause a short circuit simulation error.

—specifically the adjustable version—often requires an external library to simulate accurately. These libraries typically consist of two critical files: : Contains the graphical component data for the schematic.
