Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the fixed 1.8V output matches system requirements. Validate package marking against the datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8V rail is required at currents up to 400mA. The synchronous design offers better efficiency than non-synchronous alternatives. The small footprint suits space-constrained layouts. Verify input voltage does not exceed 5.5V. Consider thermal performance under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX1921 family of low-voltage step-down converters. It shares functional similarities with other Maxim Integrated PMICs but is distinguished by its specific 1.8V fixed output and 400mA current rating. The EUT18 suffix denotes the specific voltage variant and package type.
