What sets this regulator apart is its comprehensive protection system. Built-in safeguards against over-temperature conditions, reverse polarity, and short circuits ensure long-term reliability even in challenging operational scenarios. The 68dB PSRR (Power Supply Rejection Ratio) at 120Hz guarantees clean output voltage with minimal ripple, making it ideal for noise-sensitive applications.
Engineers will appreciate the device's 40mA maximum supply current draw, which enables efficient system power management. The through-hole TO-220-3 package provides excellent thermal dissipation characteristics while maintaining compatibility with standard PCB layouts. This combination of features makes the L4941BV particularly well-suited for industrial control systems, embedded power solutions, and automotive electronics where stability and durability are paramount.
Performance Advantages
Thermal Management: The integrated thermal shutdown mechanism automatically protects against overheating, allowing safe operation in high-temperature environments.
Energy Efficiency: With just 0.7V dropout voltage at full 1A load, this regulator maintains regulation while minimizing power losses compared to traditional linear regulators.
Design Flexibility: While featuring fixed 5V output, its compact footprint and standard pin configuration enable easy integration into existing designs without requiring external feedback components.
Whether you're developing test equipment needing stable reference voltages or building industrial machinery requiring robust power conditioning, the L4941BV delivers consistent performance. Its combination of mechanical durability in the TO-220 package with comprehensive electrical protection features makes it a preferred choice for designers prioritizing system reliability.
