REF3330AIDCKR

Overview

The REF3330AIDCKR is a fixed series voltage reference from Texas Instruments, providing a precise 3 V output. It features an initial accuracy of ±0.15% and a temperature coefficient of 30 ppm/°C. The device operates with a low quiescent current of 3.9 µA and supports a maximum input voltage of 5.5 V. It delivers up to 5 mA of load current and functions within a temperature range of -40°C to +125°C. The component is housed in a compact SC-70 (SOT-23) surface-mount package.

Feature Summary

• Provides stable 3 V reference with high initial accuracy
• Ultra-low power consumption for battery applications
• Compact SC-70 surface-mount packaging

Applications

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

Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's official datasheet to confirm the reel quantity and tape specifications. Ensure compatibility with SC-70 footprints during PCB layout. Check for RoHS compliance status and moisture sensitivity levels before procurement to meet assembly requirements.

Selection Notes

Select this part when a fixed 3 V output is required with minimal power draw. The SC-70 package suits space-constrained designs. Verify that the 5 mA drive capability meets the load requirements. Consider the 30 ppm/°C drift if operating across wide thermal ranges.

Part Context

This component belongs to the REF3330 family of micropower voltage references. It shares core electrical characteristics with other variants like the REF3330AIDCKRG4 but differs in packaging or ordering suffixes. The family is designed for general-purpose precision applications requiring low noise and high stability.

Replacement Considerations

The REF3330AIDCKRG4 is a documented variant within the same product line. Verify pinout and electrical specifications match before substitution.
