Its 2.93V threshold sits just below the nominal 3.3V supply, so it asserts reset when the rail dips to about 89% of nominal — typical for monitoring a 3.3V bus with a 5% tolerance regulator. The active-high reset output means it drives the reset pin high when the monitored voltage falls below threshold; confirm your processor's reset input polarity before committing the BOM. ## Military temperature range — where this supervisor belongs That puts it into avionics, satellite power sequencing, down-hole instrumentation, and other sealed-environment boards where a commercial (-40°C to 85°C) supervisor would drift out of spec at the cold end or fail at the hot end. The SOT-23-5 package keeps the footprint small — three signal traces and a supply rail — so it fits into tight distributed-power designs without crowding the regulator output caps. ## 5ms reset timeout — what it buys the downstream MCU The reset timeout has a minimum of 5ms. For a typical Cortex-M or other 32-bit MCU with a fast-starting internal oscillator, 5ms is adequate margin; if the board has a large capacitive load or a slow-starting external crystal, verify that 5ms minimum is sufficient for your power-up sequence. The base product number TPS3837 covers multiple threshold and package variants, so if a future BOM revision needs a different trip point, the pin-compatible sibling in the same SOT-23-5 footprint is a straightforward swap.","metaTitle":"TI TPS3837K33MDBVREP Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3837K33MDBVREP Simple Reset/Power-On Reset IC.
