High-Performance Linear Voltage Regulation for Automotive Applications
The LDK130M33R from STMicroelectronics represents a new benchmark in automotive-grade linear voltage regulation technology. Engineered for precision and reliability in demanding environments, this fixed-output regulator delivers 3.3V at up to 300mA while maintaining exceptional stability and efficiency. Its advanced design features a low dropout voltage of just 0.4V at full load, ensuring optimal performance even in voltage-sensitive automotive systems.
Advanced Power Management Features
With its 55dB PSRR across frequencies from 120Hz to 10kHz, this regulator effectively suppresses noise and ripple for clean power delivery to sensitive electronics. The integrated enable control provides precise power sequencing capabilities, while comprehensive protection features including over-current and over-temperature safeguards ensure system reliability in harsh operating conditions.
Operating across the extended automotive temperature range of -40°C to 125°C, the LDK130M33R maintains stable output voltage with minimal thermal drift. Its ultra-low quiescent current of 60µA during normal operation and 120µA maximum supply current makes it ideal for power-conscious designs requiring efficient energy utilization.
