The 78D08AL-TN3-R is a three-terminal positive voltage regulator manufactured by UTC (Unisonic Technologies Co., Ltd.). It is designed to provide a fixed 8V output voltage with a specified output current capability. The regulator includes built-in protection features such as thermal overload protection and short-circuit current limiting, enhancing its reliability and preventing damage in fault conditions.

Applications:

• Power supplies for electronic circuits
• Voltage regulation in industrial equipment
• Consumer electronics
• Microcontroller power supplies
• Battery chargers

Features:

• Fixed 8V Output Voltage
• Output Current up to 100mA
• Thermal Overload Protection
• Short-Circuit Current Limiting
• Internal Short Circuit Current Limit

Benefits:

• Provides a stable and regulated 8V output voltage.
• Protects the regulator and the load from thermal overload.
• Prevents damage from short-circuit conditions.
• Simplifies power supply design with minimal external components.
• Offers a cost-effective solution for voltage regulation.

Additional Details:

The 78D08AL-TN3-R typically requires a minimum input voltage of approximately 10.5V to maintain proper regulation. The output current capability is around 100mA. It's crucial to refer to the datasheet for precise electrical characteristics, including dropout voltage, quiescent current, and thermal resistance. The regulator is available in a TO-92 package, which is suitable for through-hole mounting. A small heat sink may be required for higher output currents to prevent overheating. It is a linear regulator, so efficiency will be limited, especially with large input-output voltage differences.
