The SC-70-3 footprint is shared across many simple reset ICs, so layout reuse is straightforward. Surface-mount only. ## Lifecycle and sourcing Listed as Active with no end-of-life notice. No LTB risk for current builds. Note that this part is marked RoHS non-compliant, so verify your assembly's exemption or waiver if you are in a RoHS-regulated region.","metaTitle":"MAX803LEXR-T Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"MAX803LEXR-T is an active Simple Reset/Power-On Reset IC with 4.63V threshold, 140ms reset timeout, open-drain output, SC-70-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-70, SOT-323","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.63V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SC-70-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.85","stockQuantity":0,"priceTiers":[{"qty":163,"price":"$1.85000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a2c10f94ef5a953d4a5abfcc9259777a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX803LEXR-T obsolete or still active?","answer":"MAX803LEXR-T is listed as Active with no end-of-life notice. It remains suitable for new designs and production replenishment."},{"question":"What is the reset timeout for MAX803LEXR-T?","answer":"The reset timeout is a minimum of 140ms. This ensures the processor supply and oscillator have settled before the reset is released."},{"question":"What are the direct equivalents or replacements for MAX803LEXR-T?","answer":"The MAX803 family includes multiple threshold variants (e.g., 2.93V, 3.08V, 4.38V) in the same SC-70-3 footprint. For a 4.63V threshold, the MAX803LEXR-T is the specific variant.
