REF3330AIDCKT

Overview

The REF3330AIDCKT is a fixed voltage reference IC from Texas Instruments, delivering a precise 3 V output. It features an initial accuracy of ±0.15% and operates within a temperature range of -40°C to +125°C. The device utilizes a series topology with a maximum input voltage of 7.5 V and supports up to 5 mA output current. Packaged in a compact SC-70 (SOT-23) surface-mount housing with three pins, it offers low power consumption suitable for space-constrained designs.

Feature Summary

• Provides stable 3 V reference voltage with high initial accuracy
• Operates reliably across extended industrial temperature ranges
• Compact surface-mount package design for efficient PCB layout

Applications

• Portable battery-powered instrumentation systems
• Data acquisition modules requiring precise analog references
• Industrial process control signal conditioning circuits

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and thermal characteristics. Ensure the ordering part number matches the required package variant and accuracy grade. Confirm availability status directly with authorized distributors as supply levels fluctuate. Validate that the component meets all necessary environmental certifications for your specific application region.

Selection Notes

Select this component when a stable 3 V reference is required in minimal space. Consider the ±0.15% accuracy and low temperature coefficient for precision applications. Evaluate the 7.5 V maximum input limit against your system supply rails. Compare power consumption requirements against other family members if lower current draw is critical.

Part Context

This part belongs to the REF3330 series of micropower voltage references designed for portable and battery-operated equipment. It shares architectural similarities with other members like the REF3333 but differs in output voltage. The SC-70 package allows for automated assembly and reduced board footprint compared to larger through-hole alternatives.

Replacement Considerations

Direct substitutes include REF3330AIDCKRG4 which maintains identical electrical specifications and pin configuration. Verify package dimensions and marking codes before substitution to ensure mechanical fit.
