Overview
The TL4051AIDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.225V with an initial accuracy of ±0.1%. The device operates within a temperature range of -40°C to 85°C and features a low temperature coefficient of 50ppm/°C. It requires a minimum cathode current of 65µA and supports a maximum output current of 12mA. The component is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Fixed 1.225V output voltage with high initial accuracy
- Micropower operation with low minimum cathode current requirement
- Stable across all capacitive loads without external compensation
- Low noise and low temperature coefficient for precision applications
Applications
- Data acquisition systems
- Portable instrumentation
- Battery-powered equipment
- Precision audio circuits
Procurement Notes
Verify the specific suffix 'IDBZT' corresponds to the industrial temperature grade (-40°C to 85°C) and SOT-23-3 package configuration. Confirm that the 'A' grade designation matches the required ±0.1% initial accuracy tolerance for your design specifications. Ensure compatibility with RoHS standards if applicable to your region.
Selection Notes
Select this component when a stable, low-noise reference is needed in space-constrained designs. The fixed 1.225V output simplifies circuit design compared to adjustable variants. Consider the 65µA minimum operating current to ensure proper regulation during low-power standby modes. The SOT-23-3 package offers a small footprint suitable for dense PCB layouts.
Part Context
This part belongs to the TL4051 family of micropower shunt voltage references from Texas Instruments. It shares architectural similarities with the LM4051 but offers improved performance characteristics. The family includes adjustable versions and other accuracy grades, providing designers with options for various precision requirements and cost constraints.
Replacement Considerations
The TL4051AIM3X-ADJ/NOPB is a related adjustable variant within the same family. For direct replacement, verify pinout compatibility and thermal performance. Check datasheets for any differences in dynamic impedance or noise specifications between legacy and current production batches.
