TL4050B50IDBZT

Overview

The TL4050B50IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 50 ppm/°C. It supports a maximum cathode current of 15 mA and draws a typical quiescent current of 80 µA. The component is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with ±0.2% initial accuracy for stable reference performance.
• Designed for low-power applications with micropower consumption characteristics suitable for battery-operated systems.
• Capable of handling load currents up to 15 mA while maintaining tight thermal stability across extended industrial temperatures.

Applications

• Portable instrumentation requiring precise analog references
• Battery-powered measurement devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix IDBZT corresponds to the SOT-23-3 package and standard operating temperature range when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering quantity matches the available reel or cut-tape options provided by distributors. Cross-reference the part number against official Texas Instruments databases to validate authenticity and current production status before finalizing procurement.

Selection Notes

Select this component when a 5V reference is required in a small footprint with high accuracy. The SOT-23-3 package offers space efficiency for dense PCB layouts. Consider the 15 mA current capability if driving moderate loads directly. Evaluate the 50 ppm/°C temperature coefficient against system thermal requirements. Compare against other TL4050 variants if different voltage outputs or accuracy grades are needed.

Part Context

This part belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The series is designed to replace traditional Zener diodes in applications demanding superior stability and lower noise. The B-grade designation indicates tighter initial accuracy specifications compared to standard grades, ensuring reliable performance in critical analog signal paths.
