Overview
The TL4050C25IDBZR 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 a SOT-23-3 surface-mount package.
Feature Summary
- Provides stable 2.5 V reference voltage with 0.5% initial accuracy
- Low temperature drift of 50 PPM/C for thermal stability
- Micropower operation suitable for battery-powered applications
- Wide operating temperature range from -40°C to +125°C
Applications
- Portable instrumentation requiring precise voltage references
- Battery-powered measurement systems
- Data acquisition systems
- Industrial process control loops
Procurement Notes
Verify the specific suffix IDBZR corresponds to the SOT-23-3 package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement. Ensure the ordering part number matches the required 2.5 V output and 0.5% accuracy grade specified in the technical data.
Selection Notes
Select this component when a 2.5 V reference with 0.5% accuracy is required in a compact SOT-23-3 package. Consider the 50 PPM/C temperature coefficient for thermal environments. Compare against the LM4040 series if different accuracy or package options are needed. Verify that the 15 mA maximum shunt current meets the circuit load requirements.
Part Context
This part belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades, including the TL4050B series with 0.2% accuracy. The TL4050C25IDBZR specifically denotes the 2.5 V output variant with 0.5% tolerance in the SOT-23-3 surface-mount package.
Replacement Considerations
The TL4050C25IDBZRG4 is a lead-free version of this component. Other variants in the TL4050 family offer different output voltages or accuracy levels. Cross-reference with the LM4040 series for alternative packages or performance characteristics.
