The UA78M05IDCYRG3 is a classic fixed 5V LDO linear regulator from Texas Instruments, offering up to 500mA of output current. Known for its robustness and high 80dB PSRR at 120Hz, it effectively rejects low-frequency noise, making it a preferred choice for audio and industrial applications. The dropout voltage is 2V at 350mA, and the SOT-223-4 package provides adequate thermal dissipation. This regulator is a reliable solution for converting higher DC voltages to a stable 5V rail.
- Superior Low-Frequency Noise Rejection: 80dB PSRR at 120Hz eliminates mains hum in audio and precision circuits.
- Wide Input Voltage Range: Accepts up to 25V, offering flexibility in multi-rail systems.
- Proven Reliability: Industry-standard 78M05 series with decades of field-proven performance.
- Robust Thermal Package: SOT-223 ensures efficient heat dissipation for continuous 500mA operation.
