Additional Details

The S7808D typically requires a heat sink for thermal management, especially when operating with higher input voltages or under heavy load conditions. It's important to maintain a few volts of difference between the input and output voltages to ensure proper regulation. The device is often available in a TO-220 package. Consult the AUK Corp datasheet for detailed specifications on maximum input voltage, maximum output current, thermal resistance, and operating temperature. It is frequently used in applications needing a reliable and regulated 8V power source, such as some communication devices, test equipment, and specialized sensor systems.
