MAX6068AEUR+T

Overview

The MAX6068AEUR+T is a precision, micropower, low-dropout voltage reference from the MAX6061–MAX6068 series. It provides a fixed output voltage of 1.8V with an initial accuracy of ±0.17% and a maximum temperature coefficient of 20ppm/°C. The device operates within an input voltage range of 2.5V to 12.6V and draws a typical quiescent supply current of 90µA. It can source up to 5mA or sink up to 2mA of load current. The component is housed in a 3-pin SOT-23 package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Offers ultra-low dropout voltage and supply-independent quiescent current for efficient battery operation.
• Internally compensated design eliminates the need for external compensation capacitors.
• Capable of sourcing 5mA and sinking 2mA without requiring external biasing resistors.

Applications

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

Procurement Notes

Verify the specific suffix 'EUR+T' against official documentation to confirm the reel packaging format and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering increment requirements are met if purchasing directly from manufacturing channels. Cross-reference the manufacturer part number with local regulatory certifications before finalizing procurement.

Selection Notes

Select this component when a stable 1.8V reference is required in space-constrained designs utilizing the SOT-23 package. It is suitable for applications demanding low power consumption and high accuracy over a wide temperature range. Consider the 5mA sourcing capability for driving moderate loads directly. Evaluate the line regulation and noise specifications against the specific requirements of the downstream analog circuitry.
