AN7809 MATSUSHITA VOLTAGE REGULATOR TO-220

The AN7809, manufactured by Matsushita (now Panasonic), is a three-terminal positive voltage regulator IC housed in a TO-220 package. This robust and reliable regulator is designed to provide a stable and fixed 9V output voltage, making it an essential component in various electronic circuits requiring a consistent power supply. The AN7809 is part of the 78xx series of voltage regulators, known for their simplicity, ease of use, and built-in protection features. It is commonly used in applications where a regulated 9V supply is needed from a higher voltage source. The TO-220 package allows for efficient heat dissipation, enabling the regulator to handle moderate power levels without overheating. This makes it suitable for applications where the input voltage is significantly higher than the output voltage, resulting in substantial power dissipation.

Key features of the AN7809 include a fixed 9V output voltage, internal short-circuit current limiting, thermal overload protection, and safe-area compensation. These features protect the regulator and the connected circuitry from damage due to overcurrent, overheating, and excessive power dissipation. The AN7809 requires minimal external components for operation, typically only input and output capacitors to improve stability and transient response. This simplifies circuit design and reduces the overall cost of implementation. The AN7809 is widely used in various electronic devices, including power supplies, battery chargers, instrumentation, and control systems. It is ideal for applications where a stable 9V supply is needed for powering microcontrollers, sensors, operational amplifiers, and other electronic components.

The AN7809 operates with an input voltage range typically between 11.5V and 25V, providing a stable 9V output with a specified tolerance. Its low dropout voltage ensures that the regulator can maintain regulation even when the input voltage is close to the output voltage. The AN7809 is a reliable and cost-effective solution for providing a regulated 9V power supply in a wide range of electronic applications. Its built-in protection features and ease of use make it an excellent choice for both hobbyists and professional engineers.
