Output adjustable down to 1.25V or fixed 1.8V. ## Output voltage — adjustable or fixed 1.8V Fixed 1.8V output; adjustable variant sets any voltage from 1.25V up to 5V via external resistor divider. Quiescent current is 250 µA. ## Lifecycle and sourcing The MAX1818EUT18+T carries an Active lifecycle status — no end-of-life notice, no last-time-buy pressure. It's ROHS3 compliant, so it clears the environmental gate for EU and most global BOMs. No second-source alternate is listed in the official cross-reference, but the SOT-23-6 footprint is common enough that a pin-compatible LDO from another vendor could be qualified if supply tightens. ## Temperature grade and environment Rated for -40°C to 85°C ambient, this is an industrial-temperature part. It's at home in outdoor telecom cabinets, factory-floor sensor modules, motor-drive control boards, and any enclosure that sees seasonal temperature swings but stays below 85°C. Not qualified to AEC-Q100, so not the pick for under-hood automotive — but fine for cabin or infotainment if the customer accepts non-automotive-grade parts.","metaTitle":"MAX1818EUT18+T Linear Regulator, 500mA, SOT-23-6, Active","metaDescription":"MAX1818EUT18+T positive adjustable/fixed 1.8V LDO, 500mA output, SOT-23-6, -40°C to 85°C.
