Introducing the LDL1117S50R: High-Performance Linear Voltage Regulation
STMicroelectronics' LDL1117S50R linear voltage regulator represents the pinnacle of precision power management in compact SOT-223 packaging. This 5V fixed-output regulator combines exceptional thermal stability with advanced protection features, making it ideal for demanding applications in industrial control systems, automotive electronics, and high-reliability consumer devices.
Technical Excellence in Power Management
Operating with a maximum input voltage of 18V and delivering consistent 5V output at 1.2A current capacity, this regulator demonstrates remarkable efficiency across diverse operating conditions. Its ultra-low dropout voltage of 0.6V at full load ensures stable power delivery even in fluctuating environments. The integrated thermal shutdown and overcurrent protection mechanisms provide robust defense against common electrical stress factors.

Advanced Design Features
The LDL1117S50R incorporates STMicroelectronics' proprietary BiCMOS technology to achieve exceptional PSRR performance (87dB at 120Hz), ensuring clean power delivery even with noisy input sources. Its surface-mount SOT-223 package enables efficient heat dissipation while maintaining compatibility with standard PCB assembly processes. The device's quiescent current of just 500µA contributes to superior energy efficiency in battery-powered applications.
Industrial-Grade Reliability
Certified for operation across the full industrial temperature range (-40°C to 125°C), this regulator maintains specification integrity in harsh environments. The built-in under-voltage lockout (UVLO) circuitry prevents malfunction during power supply instability, while thermal protection safeguards against overheating in high-load scenarios. These features collectively ensure 200,000+ hours MTBF (Mean Time Between Failures) in typical applications.
