The LM7812T from TAEJIN is a classic fixed 12V linear regulator capable of delivering up to 1.5A of current. With a dropout voltage of 2V at 1A, it requires a minimum input of approximately 14V for proper regulation. The TO-220-3L package features a metal tab for efficient heat dissipation, making it suitable for continuous high-current applications. Its simple design and proven reliability make it a staple in industrial, automotive, and hobbyist power supply designs.
- High Output Current: 1.5A capability supports demanding loads like relays and motors.
- Excellent Thermal Performance: TO-220 package with metal tab allows effective heat sinking for sustained operation.
- Proven Reliability: Industry-standard 78xx series design with decades of field-proven performance.
- Low Quiescent Current: 8 mA quiescent current minimizes power waste in standby.
