Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the threshold voltage code '25' corresponds to the 2.325 V specification. Ensure compatibility with the SOT-23-3 footprint during PCB layout. Check RoHS compliance status for regulatory requirements. Validate operating temperature range against application environmental conditions.

Supervisors Selection Notes

Select this component for applications requiring low quiescent current and a fixed 2.325 V threshold. The SOT-23-3 package suits space-constrained designs. Consider the 120 ms reset timeout for system stability. Compare against other TPS3839 variants if different thresholds are needed. Ensure the input voltage stays within the 1.6 V to 6.5 V operational range.
