Overview
The TL4050A25QDBZT 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 0.1%. 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
- Delivers high-precision voltage regulation with 0.1% initial accuracy for stable reference applications.
- Designed for micropower efficiency, suitable for battery-operated and low-power systems.
- Engineered for automotive reliability with extended industrial temperature range operation.
Applications
- Automotive sensor signal conditioning
- Data acquisition systems requiring precise voltage references
- Portable instrumentation and test equipment
Procurement Notes
Verify the specific suffix QDBZT against the official Texas Instruments datasheet to confirm the SOT-23-3 package and A-grade accuracy specifications. Ensure compatibility with automotive qualification standards if used in vehicle electronics. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when a 2.5 V reference with 0.1% tolerance is required in a compact SOT-23-3 footprint. Consider the 50 PPM/C temperature coefficient for thermal stability needs. Evaluate the 15 mA maximum shunt current capability against load requirements. Verify that the -40 C to +125 C operating range meets the environmental conditions of the target application.
Part Context
This part belongs to the TL4050A series of precision micropower shunt voltage references from Texas Instruments. The series offers various output voltages and accuracy grades. The 'Q' designation indicates automotive qualification, while 'A' specifies the tighter 0.1% initial accuracy compared to standard grades. It serves as a key component in power management integrated circuits (PMIC) portfolios.
Replacement Considerations
Check for direct substitutes such as TL4050A25IDCKR or TL4050A25QDBZR, ensuring package and accuracy match. Verify pinout compatibility and electrical parameters before substitution.
