The L7912CV is a fixed negative voltage regulator from STMicroelectronics, delivering a stable -12V output with up to 1.5A of current. Housed in a TO-220 package, it offers a typical dropout of 1.1V at 1A and a quiescent current of 3mA. With 60dB PSRR at 120Hz, it effectively filters ripple, making it suitable for industrial, audio, and test equipment requiring a reliable negative rail.
- High Output Current: 1.5A capability supports demanding loads in industrial and audio systems.
- Excellent Ripple Rejection: 60dB PSRR at 120Hz ensures clean output for sensitive analog circuits.
- Robust Protection: Internal thermal shutdown and short-circuit current limiting enhance reliability.
- Standard TO-220 Package: Easy to mount on heatsinks for thermal management in high-power applications.
