TPS717-Q1

The TPS717-Q1 is a high-precision, low-dropout (LDO) voltage regulator designed for automotive applications, offering excellent thermal performance and robust protection features. It supports input voltages up to 6 V and provides a stable output voltage with a typical dropout voltage of just 200 mV at full load, ensuring efficient operation even under demanding conditions. The device is available in fixed output voltages of 1.8 V, 2.5 V, 3.0 V, and 3.3 V, allowing flexibility in system design. This regulator features a very low quiescent current of only 45 µA, making it ideal for battery-powered or always-on systems where power efficiency is critical. Its wide operating temperature range from –40°C to +125°C complies with AEC-Q100 Grade 1 qualification, ensuring reliability in harsh automotive environments. Additionally, the TPS717-Q1 includes integrated over-current protection, thermal shutdown, and reverse-battery protection, enhancing system safety and durability. Designed for use in automotive infotainment, ADAS (Advanced Driver Assistance Systems), body control modules, and telematics units, the TPS717-Q1 delivers stable power to sensitive analog and digital circuits. Its compact 3-pin SOT-23 package minimizes board space while maintaining high performance. The device also offers excellent line and load regulation—typically ±1% across all operating conditions—ensuring consistent output voltage despite variations in input or load. The TPS717-Q1 is optimized for minimal output noise and fast transient response, which is essential for powering microcontrollers, sensors, and communication interfaces in modern vehicles. With an enable pin for power management and support for external bypass capacitors, the regulator allows designers to tailor performance based on specific application needs. Its high ripple rejection (>60 dB at 1 kHz) further improves signal integrity in noisy environments. Engineered for compliance with automotive standards, this LDO ensures long-term reliability under vibration, thermal cycling, and electromagnetic interference (EMI). Texas Instruments’ proven process technology guarantees consistent performance across production volumes, making the TPS717-Q1 a trusted choice for OEMs and Tier 1 suppliers seeking dependable power solutions in vehicle electronics.
