MAX6018AEUR18+T

Overview

The MAX6018AEUR18+T is a precision, micropower voltage reference delivering a fixed 1.8V output in a compact SOT23-3 package. It operates with an input voltage range from (VOUT + 200mV) to 5.5V and consumes a maximum of 5µA supply current. The device features an initial accuracy of ±0.2% and a temperature drift of 50ppm/°C. It supports sourcing and sinking up to 1mA load current while maintaining stability with capacitive loads between 100pF and 1µF.

Feature Summary

• Ultra-low quiescent supply current that remains virtually independent of the input supply voltage
• Low-dropout operation allowing stable regulation with minimal headroom above the output voltage
• High initial accuracy suitable for precision data-acquisition and measurement applications
• Capable of both sourcing and sinking load currents without requiring external resistors

Applications

• Two-cell battery-operated systems
• Battery-monitoring equipment
• Hand-held devices
• Data-acquisition systems
• Industrial process-control systems

Procurement Notes

Verify the specific suffix 'EUR18' confirms the 1.8V output variant and 'A' grade accuracy. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the component matches the RoHS-compliant status indicated by the '+' symbol. Cross-reference the manufacturer part number against official Analog Devices or Maxim Integrated documentation to validate authenticity before procurement.

Selection Notes

Select this component when a fixed 1.8V reference is required within a tight three-pin surface-mount footprint. It is appropriate for designs where minimizing supply current is critical, such as portable battery-powered instruments. Verify that the system input voltage stays within the specified operating range to ensure proper dropout performance and line regulation.
