TL4050A41IDBZT

Overview

The TL4050A41IDBZT is a precision micropower shunt voltage reference from Texas Instruments, delivering a fixed output of 4.1V with an initial accuracy of ±0.1%. Housed in a compact SOT-23 package, it operates within a temperature range of -40°C to +85°C and features a low quiescent current of 73µA. The device supports a maximum cathode current of 15mA and maintains stability under input voltages up to 5V.

Feature Summary

• Provides high-precision voltage regulation with tight tolerance for sensitive analog circuits
• Operates efficiently at micropower levels suitable for battery-powered applications
• Utilizes a compact surface-mount package for space-constrained designs

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-operated measurement systems
• Data acquisition channels needing precise analog references

Procurement Notes

Verify the specific suffix IDBZT against official datasheets to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Cross-reference thermal performance requirements with the specified operating temperature range before finalizing procurement decisions.

Selection Notes

Select this component when strict accuracy and low power consumption are critical. It serves as a direct replacement for similar shunt references where ±0.1% tolerance is required. Consider the 15mA current limit when designing biasing networks for downstream circuitry.

Part Context

Part of the TL4050 series, designed for general-purpose precision applications. It complements other Texas Instruments voltage references by offering a balance between high accuracy and minimal power draw in a standard small-outline transistor package.

Replacement Considerations

Check for equivalent parts like LM4040A41IDBZT or TL4050 variants with different tolerances if ±0.1% is not strictly necessary. Verify pinout compatibility and thermal characteristics before substituting.
