Reliable Low-Dropout Voltage Regulation for Modern Electronics
STMicroelectronics' LD39050PU25R linear voltage regulator delivers exceptional performance in compact power management systems. This 2.5V fixed-output regulator combines high precision with robust protection features, making it ideal for battery-powered devices and portable electronics requiring stable voltage regulation at up to 500mA output current.
Advanced Power Management Technology
Designed with ST's proprietary VIPower M0-3 technology, this LDO regulator achieves remarkable efficiency through its 0.4V dropout voltage at full load. The 50µA quiescent current and 200µA maximum supply current ensure minimal power loss, while the 65dB PSRR (1kHz-10kHz) maintains clean output voltage even under varying load conditions. Its 6-VDFN exposed pad package provides excellent thermal dissipation for high-reliability applications.

Comprehensive Protection System
The LD39050PU25R incorporates multiple safety features: integrated over-current protection prevents damage from load faults, thermal shutdown safeguards against overheating, and short-circuit protection ensures reliability in demanding environments. The built-in power good flag and enable control provide system designers with critical status monitoring capabilities for enhanced power management.
This automotive-grade regulator meets stringent industrial requirements with its AEC-Q100 qualification and RoHS compliance. Its surface-mount 6-DFN (3x3) package enables space-saving designs while maintaining high performance in harsh operating conditions. Typical applications include portable medical devices, industrial sensors, automotive electronics, and communication equipment where stable voltage regulation is critical.
