TPS723-Q1

The TPS723-Q1 is a low-dropout (LDO) linear regulator designed for automotive applications, offering high precision and robust performance under demanding conditions. It provides a stable output voltage with a maximum dropout of 250 mV at 1 A load current, ensuring reliable operation even when input voltage is close to the output level. The device supports an input voltage range from 2.7 V to 5.5 V, making it suitable for various power supply scenarios in vehicle electronics. This regulator features ultra-low quiescent current—typically 60 μA—which enhances system efficiency, especially during idle or sleep modes common in modern automotive systems. Its output voltage accuracy is maintained within ±2% over line, load, and temperature variations, providing consistent performance across a wide operating range from –40°C to +125°C. The TPS723-Q1 includes comprehensive protection mechanisms such as thermal shutdown, current limit, and reverse battery protection, which contribute to its reliability in harsh environments. Designed to meet AEC-Q100 Grade 1 qualification standards, the TPS723-Q1 is ideal for use in infotainment systems, ADAS (Advanced Driver Assistance Systems), body control modules, and other safety-critical automotive electronics. Its compact 3mm × 3mm SON package minimizes board space while maintaining excellent thermal performance, enabling efficient integration into densely populated PCB designs. The device supports both fixed and adjustable output voltages, allowing flexibility in system design. With a fast transient response and low output noise (< 25 μV RMS), it ensures clean power delivery to sensitive analog and digital components. Additionally, the TPS723-Q1 offers a soft-start function to reduce inrush current during startup, preventing stress on the power source and improving overall system stability. Engineered for automotive-grade durability, this LDO regulator combines high efficiency, low noise, and advanced protection features to deliver robust performance in electrically noisy and thermally challenging environments typical of modern vehicles.
