Product details

1.14V threshold supervisor — obsolete, sourced on request

The 100ms minimum reset timeout gives the downstream processor time to initialize after the supply crosses the threshold.

Obsolete — no direct replacement on record

For existing BOM lines, the only sourcing path is through independent distribution — surplus or new-old-stock inventory. The SOT-23-5 package and 1.14V threshold are specific enough that a drop-in substitute from another supplier requires careful parametric review.

Industrial temperature grade, SOT-23-5 footprint

Surface mount only.

Frequently asked questions

What is the replacement for TPS3128E12DBVR?

Any substitute must match the 1.14V threshold, active low open drain output, 100ms timeout, and SOT-23-5 footprint. Parametric cross-reference against current TI supervisor family parts is recommended before committing a BOM change.
