It can be configured as either an adjustable output (down to 1.25 V) or a fixed 5 V regulator, making it flexible for a range of post-regulation tasks in portable or industrial gear. The dropout voltage maxes out at 0.22 V at full load, so a 5.5 V input rail still holds regulation through a mild sag — useful when the input comes from a 5 V bus with some ripple or a battery that droops under load. ## Dropout and quiescent current — sizing the headroom At 500 mA the dropout is 0.22 V max, meaning the input must stay at least 0.22 V above the output to maintain regulation. For a fixed 5 V output, that translates to a minimum input around 5.22 V under load. The quiescent current is 250 µA, which is moderate for a 500 mA LDO — not the lowest-Iq option for always-on sense circuits, but fine for powering analog or logic rails where the load current dominates the power budget. Enable and Power Good control features let you sequence the rail and monitor its status, handy in multi-rail designs where the downstream IC needs a valid supply flag before release from reset. ## Protection and operating range Built-in protection covers over-current, over-temperature, and short-circuit events, which covers the usual fault scenarios in a field-replaceable design. The operating temperature spans -40°C to 85°C, so it is rated for industrial environments — motor drives, outdoor telecom enclosures, or factory-floor sensors that see seasonal temperature swings. The SOT-23-6 package is a small outline, easy to hand-solder or reflow, and the SOT-6 supplier device package means the footprint is consistent across multiple LDOs in this family. ## Lifecycle and sourcing The MAX1818EUT50+T carries an active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX1818EUT50+T LDO Regulator, 500mA, SOT-23-6","metaDescription":"MAX1818EUT50+T positive LDO regulator, 500mA output, 0.22V dropout at 500mA, adjustable/fixed 5V output, SOT-23-6, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable (Fixed)","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Control Features":"Enable, Power Good","Current - Output":"500mA","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Input (Max)":"5.5V","Voltage Dropout (Max)":"0.22V @ 500mA","Voltage - Output (Max)":"5V","Supplier Device Package":"SOT-6","Current - Quiescent (Iq)":"250 µA","Voltage - Output (Min/Fixed)":"1.25V (5V)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.76000","currency":"USD"},{"qty":10,"price":"$3.38000","currency":"USD"},{"qty":25,"price":"$3.19520","currency":"USD"},{"qty":100,"price":"$2.76900","currency":"USD"},{"qty":250,"price":"$2.62700","currency":"USD"},{"qty":500,"price":"$2.35720","currency":"USD"},{"qty":1000,"price":"$2.13000","currency":"USD"},{"qty":2500,"price":"$2.13000","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1818.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MAX1818EUT50+T be used as a replacement for MAX1818EUT?","answer":"The MAX1818EUT50+T shares the same base part number family (MAX1818) and the same SOT-23-6 footprint.
