TL4050C25QDBZR

Overview

The TL4050C25QDBZR 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 0.5%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and is housed in an SOT-23-3 surface-mount package.

Feature Summary

• Provides stable precision voltage reference performance suitable for high-accuracy applications
• Designed for low power consumption with micropower operating characteristics
• Capable of handling load currents up to 15 mA for flexible circuit integration

Applications

• Portable instrumentation systems requiring precise voltage standards
• Data acquisition circuits needing stable reference sources
• Battery-powered equipment optimizing for low current draw

Procurement Notes

Verify the specific suffix QDBZR corresponds to the required automotive qualification and SOT-23-3 packaging configuration. Confirm that the 0.5% initial accuracy meets the design tolerance requirements. Ensure the 50 PPM/°C temperature coefficient aligns with thermal stability needs across the specified operating temperature range.

Selection Notes

Select this component when a 2.5 V fixed output is required alongside strict space constraints provided by the SOT-23-3 package. Consider the 0.5% accuracy and 50 PPM/°C drift if higher precision grades like the TL4050A series are not necessary. Evaluate the 15 mA current capability against the expected load requirements of the reference circuit.

Part Context
