REF2930AIDBZT

Overview

The REF2930AIDBZT is a precision series voltage reference from Texas Instruments, delivering a fixed output of 3 V. It features an initial accuracy of 2% and a temperature coefficient of 100 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 25 mA. It consumes a typical supply current of 42 µA, with a maximum rating of 50 µA. Designed for surface-mount installation in a SOT-23-3 package, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides stable 3 V reference output with 2% initial accuracy
• Low power consumption suitable for battery-operated systems
• Operates over extended industrial temperature range

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the SOT-23-3 cut tape or reel packaging configuration required for your assembly process. Confirm that the 2% accuracy class meets your circuit tolerance requirements. Ensure input voltage remains below the 5.5 V maximum limit during operation. Check RoHS compliance status if environmental regulations apply to your manufacturing facility.

Selection Notes

Select this component when a 3 V reference is needed with moderate accuracy (2%) and low quiescent current. It is suitable for applications where space is limited due to the compact SOT-23-3 footprint. Consider higher accuracy variants like the REF30xx series if tighter tolerances are required. Evaluate thermal management needs given the 125°C maximum operating temperature.

Part Context

This part belongs to the REF29xx family of low-power, precision voltage references from Texas Instruments. These devices are designed for general-purpose applications requiring a stable reference voltage in small packages. The REF2930 specifically targets the 3 V output segment, offering a balance between performance and power consumption for portable electronics.

Replacement Considerations

Direct substitutes include other Texas Instruments parts from the same family with different output voltages or accuracies, such as REF2933AIDBZT for 3.3 V. Cross-brand replacements require careful verification of pinout compatibility, output voltage tolerance, and temperature coefficient specifications.
