1.12V threshold — what it locks for the supply rail
The TPS3808G12DBVT: The reset output is active-low, open-drain, so it can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail. The reset timeout is adjustable via an external capacitor, giving the designer control over the power-good delay after the supply stabilises.
125°C junction — rated for the hot zones
The reset assertion remains valid through the full 125°C junction limit.
SOT-23-6 — footprint and fit
The part comes in a 6-pin SOT-23 package, surface-mount. The open-drain output and single-voltage monitoring keep the pin count low.
