Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure the SOT-323 footprint matches your PCB design requirements. Confirm that the 1.25V output aligns with your system's reference needs.

Selection Notes

Select this component when low power consumption and high precision are critical in space-constrained designs. The wide temperature range makes it suitable for industrial environments. Compare against other TS33 family members if different output voltages or accuracies are required.

Part Context

Part of the TS33 family of low-power series voltage references, designed for applications requiring stable reference voltages with minimal current draw. The TS3312ACR specifically offers a fixed 1.25V output, distinguishing it from adjustable or higher-voltage variants in the same product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the TS33 series offering similar accuracy and power characteristics. Verify that any replacement maintains the SOT-323 package and meets the -40°C to +125°C operating temperature specification.
