REF3450TIDBVR

Overview

The REF3450TIDBVR is a fixed-output series voltage reference from Texas Instruments, providing a stable 5 V output. It features an initial accuracy of ±0.05% and a temperature coefficient of 6 ppm/°C. The device operates within an input voltage range of 5.5 V to 12 V and draws a typical quiescent current of 72 µA. It is housed in a compact SOT-23-6 surface-mount package and supports operation across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides a precise 5 V fixed output with high initial accuracy
• Features low power consumption suitable for battery-operated systems
• Offers low drift characteristics over temperature variations
• Utilizes a small-footprint SOT-23-6 package for space-constrained designs

Applications

• Data acquisition systems requiring stable reference voltages
• Industrial process control instrumentation
• Portable test and measurement equipment
• Automotive sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix IDBVR confirms the SOT-23-6 package and reel/cut-tape availability. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required output voltage and accuracy grade. Check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when a 5 V reference is required with low noise and high precision. Compare against other REF34xx variants if different output voltages or tighter temperature coefficients are needed. Consider the 72 µA quiescent current for power budget calculations. Ensure the input voltage remains above 5.5 V for proper regulation.

Part Context

This part belongs to the REF34xx family of low-drift, low-power voltage references from Texas Instruments. The family includes various fixed output voltages such as 2.5 V, 3.0 V, 3.3 V, 4.096 V, and 5.0 V. All members share similar performance characteristics including high accuracy and small package options.
