Overview
The TL4051B12IDBZR is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 50 ppm/°C. It requires a minimum operating current of 60 µA and supports a maximum cathode current of 12 mA. The component is housed in a SOT-23-3 surface-mount package.
Feature Summary
- Provides stable fixed output voltage without requiring external capacitors for stability across all capacitive loads
- Delivers low noise performance suitable for precision analog applications
- Offers high initial accuracy with low temperature drift characteristics
Applications
- Data acquisition systems
- Portable instrumentation
- Battery-powered equipment
- Precision audio circuits
Procurement Notes
Verify the specific suffix IDBZR corresponds to the SOT-23-3 package and standard industrial temperature range. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as supply chain conditions vary. Ensure ordering documentation matches the exact part number to avoid substitution errors.
Selection Notes
Select this component when a fixed 1.225 V reference with ±0.2% tolerance is required in a compact SOT-23-3 footprint. It is suitable for designs needing low quiescent current and stability under varying capacitive loads. Consider alternative grades if tighter accuracy or extended temperature ranges are necessary.
Part Context
This part belongs to the TL4051 family of micropower shunt voltage references from Texas Instruments. The family includes adjustable versions and other fixed voltage options with varying accuracy grades (A, B, C). The TL4051 series is designed for space-constrained applications requiring reliable reference voltages.
Replacement Considerations
Compatible substitutes include LM4041B12IDBZR and TL4051C12IDBZR. Verify pinout compatibility and electrical specifications such as temperature coefficient and initial accuracy before substituting.
