3.08 V threshold — the reset trip point that matters
Its 3.08 V threshold means the reset asserts when the supply drops to that level, giving the downstream MCU or logic a clean reset before the rail falls out of spec. The active-low push-pull output drives the processor's reset pin directly — no external pull-up resistor needed, and the totem-pole stage delivers fast, glitch-free edges.
140 ms reset timeout — why it matters for power-up sequencing
This prevents boot failures from a rail that hasn't fully settled or a clock that hasn't locked. For a typical 3.3 V MCU system, that 140 ms window is comfortable margin for a ceramic-cap regulator start-up.
