TLV702-Q1

The TLV702-Q1 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments, designed for automotive and industrial applications requiring high reliability and efficiency. It delivers a stable output voltage with a maximum dropout of 150 mV at 100 mA, enabling operation from input voltages as low as 1.8 V while maintaining precise regulation. The device supports an input voltage range from 1.8 V to 5.5 V, making it suitable for systems powered by single-cell batteries or multi-voltage power rails. This LDO features ultra-low quiescent current—just 40 µA in active mode and 0.1 µA in shutdown mode—which significantly extends battery life in portable and energy-sensitive applications. Its integrated over-current protection, thermal shutdown, and output short-circuit protection enhance system robustness and safety, particularly in harsh environments such as automotive electronics where electromagnetic interference (EMI) and temperature extremes are common. The TLV702-Q1 is qualified to AEC-Q100 Grade 1 standards, ensuring reliability under extreme operating conditions ranging from -40°C to +125°C. This makes it ideal for use in engine control units (ECUs), infotainment systems, ADAS components, and other vehicle subsystems that demand consistent performance across wide temperature ranges. Additionally, its small 3-pin SOT-23 package minimizes PCB footprint, supporting compact and efficient board designs. Functionally, the TLV702-Q1 provides fast transient response, minimizing output voltage deviations during sudden load changes—an essential trait in digital signal processing and microcontroller-based systems. With a fixed output voltage of 3.3 V and excellent line and load regulation (typically ±1%), it ensures clean and stable power delivery to sensitive analog and digital circuits. The device also includes an enable pin for power management, allowing seamless integration into systems with multiple power domains or sleep modes. Designed for high-performance and long-term stability, the TLV702-Q1 meets stringent automotive quality requirements while offering superior efficiency and simplicity compared to traditional linear regulators. Its combination of low quiescent current, robust protection features, and wide operating range makes it a preferred choice for engineers seeking reliable power solutions in demanding environments.
