The 78M12A from Slkormicro is a fixed 12V linear regulator capable of 500mA output. With a 2V dropout and 6mA quiescent current, it offers reliable performance for industrial and consumer applications. The TO-252 package ensures efficient heat dissipation, while 80dB PSRR at 120Hz delivers clean DC power.
- Robust Ripple Rejection: 80dB PSRR at 120Hz eliminates mains frequency noise, ideal for audio and measurement circuits.
- Thermal Protection: Internal current limiting and thermal shutdown safeguard against overloads.
- Wide Input Tolerance: Accepts up to 25V input, providing design flexibility for multi-rail systems.
- Surface-Mount Efficiency: TO-252 package simplifies assembly and improves thermal performance vs through-hole.
Industrial Control Panels
Provides a stable 12V rail for PLCs and relay drivers, with 80dB PSRR at 120Hz rejecting 50/60Hz mains hum.
LED Lighting Drivers
Regulates 12V for constant-voltage LED strips, ensuring consistent brightness and protecting against input surges up to 25V.
Automotive Aftermarket
