TL4050A10IDBZR

Overview

The TL4050A10IDBZR 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%. 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 is housed in a SOT-23-3 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with 0.1% initial accuracy for critical analog circuits.
• Maintains stable performance across extended industrial temperature ranges up to 125°C.
• Operates with low quiescent current consumption suitable for battery-powered applications.

Applications

• Precision data acquisition systems requiring stable reference voltages
• Industrial process control instrumentation
• Medical equipment signal conditioning

Procurement Notes

Verify the specific suffix 'A' indicates the 0.1% accuracy grade and 'Q' denotes automotive qualification if present, as these define functional parameters. Confirm the SOT-23-3 package matches the design footprint. Ensure the operating temperature range meets the application's thermal requirements before finalizing procurement.

Selection Notes

Select this component when 10 V precision is required with tight tolerance constraints. The 0.1% accuracy distinguishes it from standard variants. Consider the SOT-23-3 package size for space-constrained PCB layouts. Verify that the 15 mA shunt current capability aligns with the circuit's load requirements.

Part Context

This part belongs to the TL4050 family of micropower shunt voltage references. It shares the core architecture with other variants but is distinguished by its specific 10 V output and 0.1% accuracy grade. The family offers various voltage options and accuracy levels to suit different precision requirements.

Replacement Considerations

Direct substitutes include other TL4050 series parts with matching 10 V output and 0.1% accuracy, such as LM4040DIM3X-10/NOPB. Verify package compatibility and temperature range specifications when evaluating alternatives.
