It operates from a 4.7 V to 12.6 V input rail and supplies up to 500 µA to the load — enough to bias the reference input of a successive-approximation ADC, set the common-mode point on an op-amp chain, or provide a stable threshold for a comparator. The SOT-23-3 package (TO-236-3 / SC-59 footprint) keeps board area small, and the -40°C to +85°C operating range suits industrial control, outdoor telecom, and automotive cabin-domain electronics where a clean, drift-stable voltage is needed without an external trim pot. ## 4.5 V fixed output — what it means for the BOM The 4.5 V output is fixed — no feedback pin or trim network. That simplifies the BOM but locks the reference to this one rail. ## Package and mounting Housed in a standard SOT-23-3 (TO-236-3 / SC-59) surface-mount package, the MAX6045AEUR+T shares a footprint with countless other three-terminal references and regulators. No thermal pad or exposed paddle — the SOT-23-3 dissipates through the leads and board copper, adequate at the 500 µA output level since the part rarely dissipates more than a few milliwatts. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"MAX6045AEUR+T Voltage Reference, 4.5V ±0.2% SOT-23-3","metaDescription":"Maxim MAX6045AEUR+T series voltage reference: 4.5V fixed output, ±0.2% accuracy, 20ppm/°C drift, SOT-23-3, -40°C to +85°C.
