TL4050B50IDBZR

Overview

The TL4050B50IDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5 V 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 shunt current of 15 mA and consumes a typical cathode 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 tight initial tolerance specifications for accurate circuit referencing.
• Designed for low-power applications through minimized quiescent current consumption suitable for battery-operated systems.
• Capable of maintaining stable performance across extended industrial temperature ranges.

Applications

• Portable instrumentation requiring precise analog-to-digital conversion references
• Battery-powered measurement devices needing low standby current
• Industrial control systems utilizing external reference standards

Procurement Notes

Verify the specific suffix IDBZR confirms the SOT-23-3 package and reel packaging format. Ensure the B grade designation matches the required 0.2% accuracy specification for your design. Confirm RoHS compliance status if restricted materials are prohibited in your manufacturing process. Check for automotive qualification requirements, as this specific part number is not AEC-Q100 certified.

Selection Notes

Select this component when a fixed 5 V reference is needed with superior initial accuracy compared to standard zener diodes. The low operating current makes it suitable for space-constrained designs where power efficiency is critical. Consider the thermal management capabilities of the SOT-23-3 package for high ambient temperature environments.

Part Context

This device belongs to the TL4050 series of precision shunt voltage references from Texas Instruments. The series offers various output voltages and accuracy grades to support diverse power management needs. The TL4050 family is designed to replace traditional discrete zener-based solutions with higher stability and lower noise characteristics.

Replacement Considerations

Direct substitutes include other TL4050 variants with different accuracy grades or output voltages, such as TL4050A50IDBZR or TL4050C50IDBZR. Cross-reference with similar shunt references from other manufacturers only if pin compatibility and electrical parameters match exactly.
