That 0.8V floor means it can power a 1.8V I/O rail directly when the FB pin is tied to the internal divider, or you can set the output anywhere between 0.8V and 4.5V with an external resistor pair — useful when the same BOM position must serve a 1.2V core on one build and a 3.3V analog rail on the next. ## 500 mA output and 400 µA quiescent — the load-vs-standoff trade The 400 µA quiescent current is the regulator's own draw independent of load; for a device that spends most of its time in active mode (not shutdown), that Iq is moderate — a sensor node pulling 10 mA from the output sees only 4% overhead from the regulator itself. Protection features include over-current, over-temperature, and short-circuit — the over-current limit folds back the output to prevent thermal runaway, and the thermal-shutdown threshold (typically 160°C junction) protects against sustained overloads. The Enable and Power Good control pins let a supervisor sequence the rail: PG asserts when the output reaches ~92% of its nominal value, which is the signal to release the downstream reset. It is ROHS3 compliant, so no exemption-based paperwork is needed for EU-market builds.","metaTitle":"MAX1806EUA18+ LDO Regulator, 500mA, 8-uMAX-EP","metaDescription":"MAX1806EUA18+ linear regulator, 0.8V (1.8V fixed) or adjustable output, 500mA, 400µA Iq, -40°C to +85°C, 8-uMAX-EP.
