What the 2.63V threshold and 140ms timeout mean for your rail
The MAX6381XR26D3+T is a single-channel supervisor that monitors a 2.63V threshold — that threshold sits just below the nominal 2.7V or 2.8V rails common in low-voltage core supplies, so it catches a brownout before the logic starts bit-flipping.
The SC-70-3 (SOT-323) package is a 3-lead surface-mount footprint that shares the same land pattern as the industry-standard SOT-323 — no special pad geometry needed.
