The AN78N08 is a three-terminal positive voltage regulator manufactured by Panasonic. It's designed to provide a stable 8V output voltage from a higher input voltage. This series of voltage regulators are commonly used in various electronic circuits to ensure a constant voltage supply for sensitive components.

Applications

• Power supplies: Used in linear power supplies to regulate the output voltage.
• Microcontroller circuits: Provides a stable voltage supply for microcontrollers and other digital logic circuits.
• Battery chargers: Used to regulate the charging voltage for batteries.
• Audio amplifiers: Supplies a regulated voltage for audio amplifier circuits.
• Instrumentation: Used in test and measurement equipment to provide a stable voltage reference.

Features

• Fixed output voltage: Provides a fixed 8V output voltage with high accuracy.
• Overload protection: Includes built-in overload protection to prevent damage from excessive current draw.
• Short-circuit protection: Protects the regulator from damage in the event of a short circuit.
• Thermal shutdown: Shuts down the regulator if the temperature exceeds a safe limit.
• Simple to use: Requires only a few external components for operation.

Benefits

• Stable voltage supply: Provides a constant voltage output, ensuring reliable operation of electronic circuits.
• Protection against overloads and short circuits: Protects the regulator and other components from damage.
