The LM7905 is a negative voltage regulator from the LM79xx series that provides a stable -5V output. It is capable of delivering up to 1.5A of output current, making it ideal for applications requiring consistent negative voltage. This IC is available in a TO-220 package and includes built-in protection features such as thermal overload, short circuit protection, and current limiting, ensuring safe and reliable operation under various conditions.
For optimal performance, the LM7905 requires external capacitors for stabilization — a 2.2uF ceramic capacitor at the input and a 1uF ceramic capacitor at the output. These capacitors should be placed as close as possible to the IC's terminals for effective operation. Since the IC can generate significant heat when delivering high current, it is recommended to use a heat sink to avoid overheating and ensure long-lasting, efficient performance.
