TL4050B10QDBZR

Overview

The TL4050B10QDBZR 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 ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 50 ppm/°C. It is housed in a SOT-23-3 surface-mount package and supports a maximum shunt current of 15 mA.

Feature Summary

• Provides high-precision voltage regulation with ±0.2% initial accuracy for stable reference applications.
• Designed for low-power operation, suitable for battery-powered and energy-efficient systems.
• Capable of maintaining performance across an extended industrial temperature range.

Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix QDBZR against the manufacturer's official datasheet to confirm automotive qualification status and pinout compatibility. Ensure the ordering part number matches the required tolerance and package type exactly. Cross-reference with the latest product change notifications to confirm manufacturing origin and material compliance before finalizing procurement orders.

Selection Notes

Select this component when a 10 V fixed reference with ±0.2% accuracy is required in a compact SOT-23-3 package. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Verify that the system can accommodate the maximum 15 mA shunt current without exceeding power dissipation limits in the chosen enclosure.

Part Context

This device belongs to the TL4050 series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'B' designation indicates the ±0.2% accuracy grade, while 'Q' typically denotes automotive qualification. The 'DBZR' suffix specifies the SOT-23-3 package and reel packaging configuration.

Replacement Considerations

Compatible alternatives include other TL4050 variants with matching 10 V output and ±0.2% accuracy, such as TL4050B10IDBZR or TL4050B10QDCKR, provided package and qualification requirements align. Verify pinout compatibility and thermal characteristics before substitution.
