TPS7A16-Q1

The TPS7A16-Q1 is a low-dropout (LDO) voltage regulator designed for automotive applications, manufactured by Texas Instruments. It provides a stable output voltage with high accuracy and low quiescent current, making it ideal for power-sensitive systems in vehicles. The device supports an input voltage range from 2.5 V to 5.5 V and delivers a fixed 3.3 V output with a maximum load current of 1 A. Its ultra-low dropout voltage—typically just 100 mV at full load—ensures efficient operation even under varying input conditions, such as those found in automotive environments with fluctuating battery voltages. This regulator features integrated protection mechanisms including thermal shutdown, current limit, and reverse-battery protection, which enhance system reliability and safety. It also includes a precision enable pin that allows for accurate control of the power-up sequence, reducing system complexity and improving overall performance. The TPS7A16-Q1 operates with a very low quiescent current of only 80 µA, minimizing power consumption during standby or idle modes—an essential trait for always-on automotive electronics like infotainment, telematics, and ADAS systems. Designed to meet AEC-Q100 Grade 1 qualification standards, the TPS7A16-Q1 is suitable for harsh automotive environments, offering robustness against temperature extremes (-40°C to +125°C), vibration, and electromagnetic interference. Its compact 5-pin WSON package ensures minimal board space usage while maintaining excellent thermal performance. The device supports fast transient response, ensuring stable output during sudden load changes—a critical requirement in modern vehicle electronics where multiple modules may draw power simultaneously. Common applications include powering microcontrollers, sensors, communication modules, and other digital circuits in automotive systems such as dashboard controls, camera modules, and electric power steering. Due to its reliable performance, low noise, and compliance with automotive standards, the TPS7A16-Q1 is widely adopted in next-generation vehicle designs aiming for enhanced functionality, safety, and energy efficiency.
