TL4050A10QDBZT

Overview

The TL4050A10QDBZT 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.
• Optimized for low-power consumption suitable for battery-operated systems.
• Engineered for automotive reliability with AEC-Q100 qualification.

Applications

• Automotive sensor signal conditioning circuits
• Data acquisition systems requiring stable reference voltages
• Portable medical instrumentation power management

Procurement Notes

Verify the specific suffix QDBZT against official Texas Instruments documentation to confirm AEC-Q100 automotive qualification status and exact pinout configuration. Ensure compatibility with your PCB footprint design for the SOT-23-3 package. Cross-reference the datasheet revision history for any recent product change notifications that may affect mechanical or electrical specifications prior to finalizing procurement orders.

Selection Notes

Select this component when a 10 V reference is required with stringent accuracy needs in automotive or industrial settings. Compare the 0.1% initial accuracy against lower-grade variants if tighter tolerance is not critical. Consider the 15 mA maximum shunt current limit to ensure adequate biasing for downstream circuitry without exceeding thermal constraints in the SOT-23-3 package.

Part Context

This part belongs to the TL4050A series of precision micropower shunt voltage references from Texas Instruments. The 'Q' designation indicates automotive grade qualification under AEC-Q100 standards. It serves as a high-reliability alternative to standard commercial grade references, offering enhanced stability and longevity for demanding operational environments while maintaining a small form factor.

Replacement Considerations

TL4050A10IDBZT: Commercial grade version lacking automotive qualification; verify temperature range requirements. LM4040: Older generation reference with potentially different noise characteristics and accuracy specs.
