Linear & Switching Voltage Regulators

UA78M08CDCYR Description

The UA78M08CDCYR from Texas Instruments is a fixed-output linear voltage regulator designed to deliver a stable 8V output at up to 500mA of continuous current. With a wide input voltage range of up to 25V, this regulator is engineered for applications requiring reliable voltage regulation in demanding environments. Its low dropout voltage of 2V (max) @ 350mA ensures efficient operation even when the input voltage approaches the output level. The device operates across a temperature range of 0°C to 125°C, making it suitable for industrial and automotive applications. Packaged in a SOT-223-4 surface-mount form factor, it is optimized for space-constrained designs.

UA78M08CDCYR Features

• High PSRR (80dB @ 120Hz): Ensures minimal output ripple, ideal for noise-sensitive circuits.
• Robust Protection: Includes over-current, over-temperature, and short-circuit safeguards for enhanced reliability.
• Low Dropout Voltage: Maximizes efficiency in low headroom conditions.
• Wide Input Range (Up to 25V): Accommodates fluctuating input sources.
• RoHS3 & REACH Compliant: Meets stringent environmental and safety standards.
• Surface-Mount (SOT-223-4): Compact footprint for PCB space savings.
• Last Time Buy Status: Available for legacy system support but transitioning to newer alternatives.

UA78M08CDCYR Applications

• Industrial Control Systems: Stable voltage supply for sensors, PLCs, and actuators.
• Automotive Electronics: Power management in infotainment, lighting, and ECUs.
• Consumer Electronics: Voltage regulation for set-top boxes, routers, and audio equipment.
• Embedded Systems: Reliable power for microcontrollers and peripherals.
• Legacy Equipment Maintenance: Ideal for repairs or upgrades of older designs requiring 8V regulation.

Conclusion of UA78M08CDCYR

The UA78M08CDCYR stands out as a high-performance linear regulator with exceptional noise suppression, robust protection features, and wide operational limits. While it is in Last Time Buy status, its combination of efficiency, compact packaging, and reliability makes it a compelling choice for legacy and new designs alike. Engineers seeking a proven 8V regulator for industrial, automotive, or embedded applications will find this device a dependable solution. For future-proof designs, consider Texas Instruments' newer alternatives with similar specifications.
