TPS1HC30-Q1

The TPS1HC30-Q1 is a high-efficiency, low-dropout linear regulator (LDO) designed for automotive applications, manufactured by Texas Instruments. It delivers stable output voltage with minimal quiescent current, making it ideal for power-sensitive systems in vehicles. The device supports an input voltage range from 2.7 V to 5.5 V, allowing compatibility with various battery and power supply configurations commonly found in automotive environments. This LDO features a maximum output current of 300 mA, enabling reliable operation for multiple load conditions while maintaining excellent line and load regulation. Its ultra-low quiescent current—typically just 6 µA—ensures minimal power consumption during idle or standby modes, which is critical for always-on vehicle systems such as sensors, infotainment modules, or microcontroller units. Additionally, the TPS1HC30-Q1 includes built-in protection mechanisms like thermal shutdown, over-current protection, and reverse battery protection, enhancing system reliability under fault conditions. Designed to meet AEC-Q100 Grade 1 qualification standards, the TPS1HC30-Q1 is suitable for harsh automotive operating environments, including wide temperature ranges from -40°C to +125°C. This robustness ensures consistent performance across diverse climates and vehicle usage scenarios. The device also offers a fast transient response, minimizing voltage droop during sudden load changes—an essential trait for maintaining signal integrity in digital circuits. In terms of packaging, the TPS1HC30-Q1 comes in a compact, thermally efficient 3-pin SOT-23 package, facilitating easy integration into space-constrained designs. Its small footprint and low component count reduce PCB area requirements and simplify layout planning. The regulator is optimized for use in advanced driver-assistance systems (ADAS), body control modules, telematics, and other automotive subsystems where stable, clean power delivery is crucial. With its combination of high efficiency, low quiescent current, comprehensive protection features, and automotive-grade reliability, the TPS1HC30-Q1 provides a dependable solution for powering sensitive electronics in modern vehicles. It supports design simplicity and long-term system stability in demanding automotive applications.
