• Precision analog circuits
• Local on-card regulation
• Industrial control systems

Features

• Fixed -8V output voltage
• Output current up to 0.5A
• Internal thermal overload protection
• Short-circuit current limiting
• No external components required

Benefits

• Provides a stable and regulated -8V supply
• Protects against overtemperature and short-circuit conditions
• Simplifies power supply design with minimal external components
• Enhances system reliability

The AN79M08F provides a fixed -8V output voltage with a current capability of up to 0.5A. It features internal thermal overload protection, which shuts down the regulator when the junction temperature exceeds a safe limit. This prevents damage to the regulator and the surrounding circuitry. The device also includes short-circuit current limiting, which reduces the output current in the event of a short circuit, protecting the regulator and the load from damage.

A key advantage of the AN79M08F is its simplicity of use. It requires no external components for basic operation, making it easy to integrate into a variety of applications. The three terminals are for input voltage, output voltage, and ground. The input voltage should be at least a few volts more negative than the desired -8V output voltage. The regulator is typically packaged in a TO-220 or similar package, which allows for easy mounting and heat sinking. It is essential to provide adequate heat sinking to ensure the regulator operates within its safe operating area, especially at higher output currents. Its robust protection features and ease of use make it a reliable choice for providing a stable negative voltage supply in many electronic systems.
