TL4050B10QDBZT

Overview

The TL4050B10QDBZT 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 maximum shunt current of 15 mA. It utilizes a SOT-23-3 surface-mount package.

Feature Summary

• Provides high-precision voltage regulation with ±0.2% initial accuracy
• Designed for low-power applications with micropower consumption characteristics
• Capable of operation across extended industrial temperature ranges

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Battery-powered instrumentation circuits

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status against the official datasheet, as standard commercial variants lack this designation. Confirm the package type matches the required PCB footprint. Ensure the operating environment aligns with the specified temperature range and power dissipation limits defined in the manufacturer's documentation.

Selection Notes

Select this component when a 10 V reference with tight tolerance is required in a compact SOT-23-3 package. Compare performance metrics such as noise and temperature coefficient against other series members if stricter stability is needed. Verify that the cathode current requirements fit within the 15 mA maximum limit for the intended circuit design.

Part Context

This part belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades. The 'B' grade denotes ±0.2% initial accuracy, while the 'Q' suffix typically signifies automotive-grade reliability standards, distinguishing it from standard commercial versions.

Replacement Considerations

Direct substitutes include other TL4050 variants with matching 10 V output and ±0.2% accuracy, such as TL4050B10IDBZT, provided the automotive qualification requirement is waived. Cross-reference pinouts and thermal characteristics before substitution.
