Procurement Notes

Verify the specific suffix 'CR' against official STMicroelectronics documentation to confirm the exact tape and reel packaging configuration and quantity per reel. Ensure the component grade matches the required industrial specifications for your application environment. Cross-reference the datasheet revision date to ensure compliance with current RoHS and Ecopack2 standards before finalizing procurement orders.

Selection Notes

Select this component when a stable 3.3 V reference is required in space-constrained designs utilizing the SOT23-3L package. It is suitable for applications demanding low power consumption without sacrificing precision, particularly where the +/-0.15% initial accuracy and 30 ppm/°C temperature coefficient are critical for system performance over the full industrial temperature range.

Part Context

The TS3333ACR belongs to the TS33 family of micropower series voltage references from STMicroelectronics. This family includes variants with different fixed output voltages such as 1.25 V, 2.048 V, 2.5 V, and 3.0 V. All members share common characteristics including low power consumption, high precision, and availability in multiple packages like QFN8, SOT23-3L, and SOT323-3L.

Replacement Considerations

Other TS33 series parts with different output voltages may serve as functional substitutes if the voltage requirement differs. Verify pinout compatibility and thermal performance when replacing with other packages in the same family.
