That delay gives the downstream processor time to finish its power-up sequence before the reset releases. Housed in a 5-pin SC-70-5 (SOT-353) package, this is a surface-mount part with a 0.65mm pitch — small enough to tuck next to the monitored rail without eating board space. No last-time-buy window, no end-of-life notice on the books.","metaTitle":"TI TPS3801E18DCKR Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3801E18DCKR simple reset/power-on reset IC.
