MAX6067BEUR+T

Overview

The MAX6067BEUR+T is a precision, micropower, low-dropout voltage reference from the MAX6061–MAX6068 series. It provides a fixed output voltage of 4.5V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C. The device operates within an extended temperature range of -40°C to +85°C and features a quiescent supply current of typically 90µA. It can source up to 5mA or sink 2mA of load current while maintaining stability without requiring an external compensation capacitor.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
• Series-mode architecture eliminates the need for external biasing resistors, offering supply current virtually independent of input voltage variations.
• Internally compensated design removes the requirement for external frequency-stabilization capacitors, saving board space in compact applications.
• Low dropout voltage capability allows efficient operation in battery-powered systems with minimal power dissipation.

Applications

• Portable Battery-Powered Systems
• Analog-to-Digital Converters (ADCs)
• Precision 3V/5V Systems

Procurement Notes

Verify the specific suffix 'EUR' corresponds to the SOT-23-3 package and tape-and-reel shipping configuration as defined in the manufacturer's ordering guide. Confirm that the '+T' designation indicates reel packaging rather than cut tape when placing orders. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the top marking 'FZFT' to validate authenticity upon receipt.

Selection Notes

Select this part when a stable 4.5V reference is required in space-constrained designs. The BEUR variant offers tighter initial accuracy compared to standard versions but higher drift than A-grade parts. Consider the 90µA quiescent current for battery life calculations. Verify that the input voltage remains above the minimum dropout threshold during all operating conditions to maintain regulation.
