STMicroelectronics STLQ015M28R Linear Voltage Regulator

STMicroelectronics STLQ015M28R: Precision Low-Dropout Voltage Regulation

Engineered for modern electronics demanding stable power solutions, the STLQ015M28R from STMicroelectronics delivers exceptional voltage regulation performance in a compact SOT23-5 package. This ultra-low quiescent current LDO (1.7 µA) combines high efficiency with advanced protection features, making it ideal for battery-powered applications where power conservation and reliability are critical.

Technical Excellence in Voltage Regulation

Operating within a -40°C to 125°C temperature range, this monolithic linear regulator maintains precise 2.8V output across varying load conditions. Its 150mA output current capacity paired with a maximum 0.3V dropout voltage at full load ensures minimal power loss - a crucial advantage for energy-sensitive designs. The device's 40dB PSRR (1kHz) effectively filters power supply noise while the integrated enable function allows for precise power management control.

Advanced Power Management Solutions

Designed with modern electronics in mind, the STLQ015M28R incorporates multiple layers of protection while maintaining minimal board space requirements. The SOT23-5 package enables efficient thermal dissipation in space-constrained applications, while the device's CMOS technology ensures fast transient response and stable operation across varying environmental conditions. Its 100kHz PSRR performance (15dB) makes it particularly suitable for RF circuits and other noise-sensitive applications.

This regulator excels in portable devices requiring extended battery life, such as IoT sensors, wearable electronics, and mobile peripherals. The combination of low dropout voltage and ultra-low quiescent current extends battery operation time while maintaining system stability. Engineers will appreciate the built-in thermal protection that prevents damage during fault conditions, eliminating the need for external protection circuitry.

Design Flexibility and Application Versatility

While optimized for 2.8V systems, the STLQ015M28R's design philosophy emphasizes adaptability. Its tape-and-reel packaging facilitates automated assembly processes, and the surface-mount configuration supports high-density PCB layouts. The device complies with RoHS standards, ensuring environmental compliance while maintaining industrial-grade reliability.
