REF3330AIDCKRG4

Overview

The REF3330AIDCKRG4 is a fixed series voltage reference IC manufactured by 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 within an input voltage range of 3.2 V to 5.5 V and supports a maximum load current of 5 mA. It consumes only 3.9 µA of supply current, making it suitable for low-power applications. The component functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SC-70-3 surface-mount package.

Feature Summary

• Delivers high precision with ±0.15% initial accuracy and low temperature drift of 30 ppm/°C.
• Optimized for energy efficiency with ultra-low quiescent current consumption of 3.9 µA.
• Capable of sourcing up to 5 mA of load current while maintaining regulation stability.

Applications

• Portable battery-powered instrumentation requiring minimal power drain
• Data acquisition systems utilizing analog-to-digital converters
• Industrial process control loops with strict accuracy requirements

Procurement Notes

Verify the specific suffix RG4 indicates tape-and-reel packaging configuration distinct from cut-tape variants. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the SC-70-3 footprint matches the target PCB layout dimensions accurately. Check for any recent product change notifications regarding marking or material composition updates.

Selection Notes

Select this component when a stable 3 V reference is required in space-constrained designs. The SC-70-3 package offers a small form factor ideal for dense layouts. Consider the 3.9 µA current draw critical for extending battery life in portable devices. Verify that the 5 mA output capability meets the downstream circuit's loading demands without exceeding thermal limits.

Part Context

This part belongs to the REF3330 family of micropower voltage references from Texas Instruments. It shares core electrical specifications with other suffixes like REF3330AIDCKT but differs in packaging format. The family targets applications needing high precision in small packages. Other members include variants with different output voltages or package types such as SOT-23.

Replacement Considerations

REF3330AIDCKT serves as a functional equivalent offering identical electrical characteristics in a cut-tape package format instead of reel packaging. Both parts share the same die and performance metrics. Selection depends primarily on manufacturing automation requirements and inventory handling preferences rather than technical differentiation.
