STMicroelectronics L7808CV-DG Linear Voltage Regulator 8V 1.5A TO-220

Introducing the STMicroelectronics L7808CV-DG Linear Voltage Regulator

In the realm of electronic components, the L7808CV-DG by STMicroelectronics emerges as a robust solution for precise power management. This fixed linear voltage regulator delivers a stable 8V output, engineered to meet the demands of diverse applications, from industrial control systems to consumer electronics. With its ability to handle up to 1.5A of current and built-in protection features, it stands as a reliable choice for engineers prioritizing performance and durability.

Key Features and Technical Specifications

The L7808CV-DG operates within a wide input voltage range, accepting up to 35V while maintaining a fixed 8V output. Its dropout voltage of 2V at 1A ensures efficiency even under fluctuating load conditions. Packaged in a TO-220-3 casing, this regulator combines compact design with superior thermal dissipation, making it ideal for space-constrained and high-power applications.

Designed for reliability, the L7808CV-DG integrates thermal shutdown and short-circuit protection, safeguarding both the regulator and connected components. Its Power Supply Rejection Ratio (PSRR) of 56dB at 120Hz ensures minimal noise interference, critical for audio equipment and precision instrumentation.

Applications and Practical Use Cases

This regulator shines in applications requiring stable voltage regulation, such as:

- Power supplies for test and measurement equipment
- Battery charging systems
- Industrial automation and control modules
- Embedded systems with sensitive analog circuits

The TO-220 package allows straightforward integration into PCB designs, while its through-hole mounting ensures mechanical stability in rugged environments.

Performance and Design Considerations

When designing with the L7808CV-DG, engineers must account for input voltage headroom and thermal management. The regulator requires at least 10V input to maintain regulation, but its 35V max input offers flexibility for variable power sources. For optimal performance, a heatsink may be necessary in high-current scenarios to prevent thermal throttling.

Complementing its technical prowess, the L7808CV-DG operates within an industrial temperature range of 0°C to 125°C, ensuring reliability in demanding environments. Its absence of external components simplifies design and reduces bill-of-materials costs.

Conclusion

The STMicroelectronics L7808CV-DG stands as a testament to efficient power management. With its combination of high current capability, inherent protection features, and ease of integration, this regulator addresses the needs of modern electronic systems. Whether in prototyping or large-scale production, it delivers the stability and durability required for today's electronics, making it a go-to choice for engineers worldwide.
