TLV7042-Q1

The TLV7042-Q1 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments, designed for automotive and industrial applications requiring high reliability and precision. It delivers a stable 2.5 V output with a maximum current of 250 mA, making it suitable for powering sensitive analog and digital circuits in demanding environments. This device features an ultra-low quiescent current of just 30 µA, which significantly enhances power efficiency—especially critical in battery-powered systems where minimizing energy consumption is essential. Its dropout voltage is as low as 180 mV at full load, allowing operation even when input voltage is close to the regulated output, thus improving system flexibility and reducing power loss. The TLV7042-Q1 includes comprehensive protection mechanisms such as thermal shutdown, over-current protection, and short-circuit protection, ensuring robust operation under adverse conditions. It also supports fast transient response, maintaining output stability during sudden load changes—a key requirement for modern microcontroller-based systems and sensor interfaces. Engineered to meet AEC-Q100 Grade 1 qualification standards, this LDO is optimized for automotive use, operating reliably across a wide temperature range from -40°C to +125°C. This makes it ideal for engine control units, infotainment systems, ADAS modules, and other vehicle electronics exposed to extreme thermal stress. With a compact SOT-23-5 package, the TLV7042-Q1 offers a space-efficient solution for densely populated PCB designs. It operates from an input voltage range of 2.7 V to 5.5 V, providing compatibility with various power sources including 3.3 V and 5 V rails commonly found in automotive and industrial systems. Its high output accuracy of ±2% over line, load, and temperature ensures consistent performance, while the low output noise of 25 µVRMS contributes to clean power delivery for noise-sensitive components like ADCs, RF modules, and precision sensors. The device also includes an enable pin for remote control of power states, enabling system-level power management strategies that further reduce idle power consumption. In summary, the TLV7042-Q1 combines high efficiency, robust protection, automotive-grade reliability, and small form factor, making it a versatile and dependable choice for power regulation in safety-critical and energy-conscious electronic systems.
