REF3025AIDBZT

Overview

The REF3025AIDBZT is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of ±0.2%. It operates within an input voltage range of 2.55 V to 5.5 V and supports a maximum load current of 25 mA. The device features a temperature coefficient of 75 ppm/°C and consumes a typical supply current of 42 µA, with a maximum of 50 µA. It functions reliably across an extended temperature range of -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides high-precision fixed voltage output with tight initial tolerance
• Operates efficiently with ultra-low quiescent current consumption
• Supports wide input voltage ranges for flexible power supply integration
• Engineered for stable performance across extended industrial temperature extremes

Applications

• Motor control drives requiring precise voltage references
• Data acquisition systems needing accurate analog-to-digital conversion references
• Portable instrumentation benefiting from low-power operation
• Industrial process control loops utilizing sensor signal conditioning

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging format, as variants exist for cut tape versus reel quantities. Ensure compatibility with RoHS3 standards if required by your manufacturing specifications. Cross-reference the exact part number with the manufacturer's latest datasheet to validate current production status and any potential design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.2% accuracy is required in a small SOT-23-3 footprint. It is suitable for applications demanding low power consumption under 50 µA and operation up to 125°C. Consider alternative REF30xx variants if different output voltages or tighter temperature coefficients are needed for your specific circuit design constraints.

Part Context

This device belongs to the REF30xx family of precision voltage references manufactured by Texas Instruments. It is categorized under PMIC (Power Management ICs) specifically as a series voltage reference. The REF3025AIDBZT variant specifically denotes the 2.5 V output version packaged in SOT-23-3, designed for space-constrained electronic designs requiring reliable voltage regulation.

Replacement Considerations

The REF3025AIDBZR is a functionally equivalent alternative differing primarily in reel packaging quantity. Verify pinout compatibility and electrical specifications match exactly before substitution. Other REF30xx series members may serve as replacements if output voltage requirements differ.
