Additional Details

The AN7906F provides a fixed -6V output voltage with a typical output current of up to 1A. The input voltage range is typically -8V to -25V. The device includes internal current limiting and thermal shutdown circuitry to protect against overloads and overheating. A small external capacitor is usually required at the input and output to improve stability and transient response. The device is commonly packaged in a TO-220 or similar package for effective heat dissipation. The high ripple rejection ensures a clean and stable output voltage, making it suitable for sensitive analog circuits. The AN7906F is designed to provide a reliable and cost-effective solution for generating a regulated negative voltage.
