This part is a basic voltage supervisor — no watchdog timer, no manual reset — just a clean brown-out reset for a single low-voltage rail. ## Industrial temp and SOT-23-5 footprint The SOT-23-5 package (SC-74A) is a common small-outline footprint that routes easily on two-layer boards; the supply pin needs a 0.1µF ceramic within 5mm for decoupling, and the open-drain output pulls up to the monitored rail or a separate 3.3V logic rail through a 10kΩ resistor. The SOT-23-5 package is widely used across TI's supervisor family, which means the supply base is broad and the part is stocked across multiple distribution channels. ## Sourcing and provenance Sourced through independent distribution, each reel is traceable to a verified supply chain. The date-code laser etch on the body should match TI's standard font and marking layout — any deviation flags a suspect part.","metaTitle":"TPS3838E18DBVT Simple Reset/Power-On Reset, 1.71V Threshold","metaDescription":"Texas Instruments TPS3838E18DBVT simple reset/power-on reset IC with 1.71V threshold, active-low open-drain output, 10ms timeout, -40°C to 85°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","Voltage - Threshold":"1.71V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838E18DBVT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS3838E18DBVT and check current pricing?","answer":"TPS3838E18DBVT is available to order through independent distribution.
