TLV700-Q1

The TLV700-Q1 is a low-dropout (LDO) voltage regulator designed for automotive applications, manufactured by Texas Instruments. It offers a fixed output voltage of 3.3 V with a maximum output current of 150 mA, making it suitable for powering sensitive digital circuits in harsh environments. The device operates over a wide input voltage range from 2.5 V to 5.5 V, ensuring compatibility with various power sources such as battery systems and alternators. This LDO regulator features ultra-low quiescent current—typically 40 µA—which enhances energy efficiency, particularly in always-on or low-power modes common in modern vehicle electronics. Its robust design includes integrated protection mechanisms such as thermal shutdown, short-circuit protection, and output overcurrent limiting, ensuring reliable operation under fault conditions. Additionally, the TLV700-Q1 supports fast transient response, maintaining stable output voltage during sudden load changes, which is critical for microcontroller and sensor interfaces. Designed to meet AEC-Q100 Grade 1 qualification standards, the TLV700-Q1 is optimized for use in automotive systems including infotainment, body control modules, ADAS (Advanced Driver Assistance Systems), and telematics units. Its small package size (SOT-23-5) allows for compact board layouts, while its high stability ensures minimal noise and ripple on the regulated output, preserving signal integrity in analog and mixed-signal circuits. The device also exhibits excellent line and load regulation, with typical values of 1.5% and 1%, respectively, contributing to consistent performance across varying operating conditions. With an extended operating temperature range from -40°C to +125°C, the TLV700-Q1 is well-suited for extreme automotive environments, including engine compartments and under-hood applications where temperature fluctuations are significant. In summary, the TLV700-Q1 combines high reliability, low power consumption, and comprehensive protection features, making it a preferred choice for safety-critical and power-sensitive applications in automotive electronics.
