STMicroelectronics LDK120PU25R Linear Regulator: Precision Power Management for Modern Electronics
In today's high-performance electronic systems, reliable voltage regulation is critical for maintaining device stability and longevity. The STMicroelectronics LDK120PU25R linear voltage regulator IC delivers exceptional performance with its 2.5V fixed output voltage and 200mA current capacity, making it an ideal solution for applications requiring precise power management in compact designs. This advanced regulator combines low dropout voltage (0.3V @ 200mA) with comprehensive protection features, ensuring optimal operation across diverse environments.
Key Technical Advantages
Engineered for efficiency, the LDK120PU25R operates with an input voltage range up to 5.5V while maintaining a stable 2.5V output. Its ultra-low quiescent current (60 µA) and shutdown current (100 µA max) significantly reduce power consumption in battery-powered applications. The device's 55dB PSRR (120Hz ~ 10kHz) provides excellent noise rejection, crucial for sensitive analog circuits and RF applications.
The advanced 6-DFN (1.2x1.3mm) package enables space-constrained designs while maintaining thermal performance. With integrated over-current and over-temperature protection, this regulator ensures robust operation in industrial environments (-40°C to 125°C operating temperature range). The enable control feature allows precise power sequencing in complex systems.
