What the 2.941V threshold means for your 3.3V rail
The TPS3106K33DBVR is a single-channel voltage supervisor that asserts a reset when the monitored supply drops below 2.941V. On a nominal 3.3V rail, that threshold sits roughly 12% below the regulated voltage — early enough to catch a brownout before the downstream logic glitches, but not so tight that noise triggers false resets. That 65ms floor is the spec to check against your power-on reset timing budget.
Package and layout — SOT-23-6
The SOT-23-6 package is a 6-pin surface-mount footprint with 0.95mm pitch — routable on a 2-layer board without micro-vias. If your BOM requires a 125°C rating, the TLV803 family extends to that range.
