Overview
The TL4050B25QDBZR 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 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 a 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 significant load variations through high shunt current capability
Applications
- Data acquisition systems requiring precise voltage standards
- Portable instrumentation benefiting from low power operation
- Battery-powered measurement devices needing stable references
Procurement Notes
Verify the specific suffix QDBZR to confirm the automotive-grade qualification and SOT-23-3 packaging configuration. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Confirm that the 2.5 V output aligns with system design needs before procurement.
Selection Notes
Select this component when a 2.5 V reference with 0.2% initial accuracy is required in a compact SOT-23-3 package. Consider the 50 PPM/C temperature coefficient for thermal stability needs. Evaluate the 15 mA shunt current limit against maximum expected load currents to ensure proper regulation under all operating conditions.
Part Context
This part belongs to the TL4050B series of precision shunt voltage references from Texas Instruments. It is designed as a drop-in replacement for older generation references while offering improved accuracy and lower power consumption. The Q prefix indicates automotive qualification, distinguishing it from standard commercial variants.
Replacement Considerations
Direct substitutes include other TL4050B series parts with matching voltage and accuracy, such as TL4050B30QDBZR or TL4050B50QDBZR, provided the output voltage difference is acceptable. Verify pinout compatibility and thermal performance when substituting.
