TL4050A10QDBZR

Overview

The TL4050A10QDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10 V with an initial accuracy of 0.1% and a temperature coefficient of 50 PPM/C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 15 mA. It is housed in a compact SOT-23-3 surface-mount package, designed for applications requiring stable voltage references in space-constrained environments.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances suitable for sensitive measurement circuits.
• Operates efficiently at micropower levels, minimizing energy consumption while maintaining stable reference performance.
• Engineered for extended thermal stability across industrial temperature ranges to ensure consistent operation.

Applications

• Portable instrumentation systems requiring low power consumption
• Data acquisition modules needing precise analog-to-digital conversion references
• Battery-powered devices utilizing efficient voltage regulation

Procurement Notes

Verify the specific suffix codes on the component marking against the official datasheet to confirm the exact voltage, accuracy grade, and packaging type. Ensure the ordering part number matches the required temperature range and package variant. Cross-reference manufacturer documentation for any recent product change notifications or lifecycle status updates before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 10 V reference with 0.1% accuracy is required in a small SOT-23-3 footprint. Consider the 50 PPM/C temperature coefficient for thermal drift requirements. Evaluate the 15 mA maximum shunt current capability against the circuit's biasing needs. Confirm compatibility with the target operating temperature range of -40°C to +125°C.

Part Context

This device belongs to the TL4050A series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'Q' designation indicates automotive qualification, while 'DBZR' specifies the SOT-23-3 package and reel packaging configuration.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as other TL4050 variants with different voltage outputs or accuracy grades. Verify that any substitute maintains the required 10 V output, 0.1% accuracy, and SOT-23-3 package form factor.
