Frequently Asked Questions
What is the output voltage and accuracy of the TL4050A50QDCKRQ1?
The TL4050A50QDCKRQ1 provides a fixed 5.0V shunt reference voltage with an initial accuracy of ±0.5% (±25mV). This precision, combined with a temperature coefficient of 50ppm/°C, ensures stable voltage reference performance across the automotive temperature range of -40°C to +125°C.
Is TL4050A50QDCKRQ1 suitable for automotive applications?
Yes. The TL4050A50QDCKRQ1 is AEC-Q100 qualified, making it fully rated for automotive use. It operates reliably from -40°C to +125°C and is commonly designed into instrument clusters, ADAS sensor modules, powertrain control units, and other automotive electronics requiring a precise voltage reference.
What package does the TL4050A50QDCKRQ1 come in?
The TL4050A50QDCKRQ1 is available in a SOT-23-5 (DCK) surface-mount package. This small 5-pin package is ideal for compact, high-density PCB layouts common in automotive and portable industrial designs.
What is the operating current range for TL4050A50QDCKRQ1?
The TL4050A50QDCKRQ1 operates over a wide cathode current range of 100µA to 15mA, allowing flexible circuit design. Its low minimum operating current of 100µA makes it well-suited for low-power and battery-operated applications where quiescent current budget is tight.
What are common alternatives to the TL4050A50QDCKRQ1?
Common alternatives include the TL4050B50QDCKRQ1 (higher 0.2% accuracy version), the REF5050 for higher-performance applications, and the LM4050 series from Texas Instruments. When selecting a replacement, match the 5.0V output, accuracy grade, temperature coefficient, package, and automotive qualification requirements.
