The LM7818 is a positive voltage regulator designed to provide a stable 18V output with an output current range of 1A to 1.5A. Manufactured in a TO-220 package, this regulator is part of the LM78xx series, making it widely available and reliable.
The IC comes with built-in short circuit protection and overheat shutdown functions, making it ideal for both commercial and experimental projects. However, a heat sink is essential to prevent overheating and ensure smooth operation. Without it, the IC will automatically shut down due to the built-in thermal protection.
