The active-low output is the standard polarity for most MCU reset pins. ## 120ms reset timeout — timing the startup sequence For a typical MCU with a 10ms to 50ms power-on ramp, this 120ms window provides enough margin that the reset de-asserts only after the supply is fully settled. The SOT-23-3 package keeps the footprint small, but the 0.95mm pitch means the PCB layout should follow the recommended land pattern for reliable solder joint formation during reflow.","metaTitle":"Texas Instruments TPS3809L30DBVTG4 Simple Reset/Power-On","metaDescription":"Texas Instruments TPS3809L30DBVTG4 Simple Reset/Power-On Reset IC.
