TL4050B25IDBZT

Overview

The TL4050B25IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 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 supports a maximum shunt current of 15 mA and draws a cathode current of 103 µA. The component is housed in a SOT-23-3 package.

Feature Summary

• Provides stable reference voltage with high initial accuracy
• Designed for low power consumption applications
• Operates across extended industrial temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix IDBZT corresponds to the SOT-23-3 package and commercial/industrial grade specifications. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement. Ensure the ordering part number matches the required tolerance and temperature rating.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.2% accuracy is required in a compact surface-mount package. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 103 µA quiescent current against system power budgets. Verify that the SOT-23-3 footprint aligns with the PCB layout constraints.

Part Context

This device belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades, including A, B, and C series options. The TL4050 series is designed to replace older zener-based references with higher precision and lower power consumption characteristics.

Replacement Considerations

LM4040BIM3X-2.5/NOPB serves as a direct pin-to-pin replacement offering similar 2.5 V output and accuracy specifications.
