Advanced Power Management with STMicroelectronics LDK120M-R
In modern electronic design, precision voltage regulation remains a cornerstone for ensuring device reliability and performance. The STMicroelectronics LDK120M-R emerges as a sophisticated solution for engineers seeking adjustable linear regulation in compact SOT-23 packaging. This 200mA low-dropout regulator combines exceptional efficiency with robust protection features, making it ideal for space-constrained applications requiring stable power delivery.
Key Technical Advantages
Operating within a 0.8V to 5.2V output range, the LDK120M-R demonstrates remarkable versatility while maintaining only 0.3V dropout voltage at maximum load. Its 5.5V absolute maximum input rating provides design flexibility, while the 60µA quiescent current ensures energy efficiency in battery-powered systems. The integrated enable control simplifies power sequencing in multi-rail architectures, complemented by comprehensive protection against over-temperature and over-current conditions.
| Parameter | Value |
| Output Current | 200mA |
| DROPOUT VOLTAGE | 0.3V @ 200mA |
| Quiescent Current | 60 µA |
| Operating Temperature | -40°C to 125°C |
Design Flexibility and Integration
Engineers benefit from the device's adjustable output configuration, which eliminates the need for multiple fixed-voltage regulators in systems requiring different voltage rails. The SOT-23-5 package enables minimal PCB footprint while maintaining thermal performance through optimized pin configuration. With 55dB PSRR across frequencies from 120Hz to 10kHz, the regulator effectively suppresses input noise without requiring extensive external filtering.
Targeted applications include portable instrumentation, IoT sensor nodes, and industrial control systems where stable voltage references are critical. The device's thermal shutdown and current limiting features provide inherent reliability advantages in harsh operating environments, reducing the need for external protection circuitry.
