MAX6520EUR+T

Overview

The MAX6520EUR+T is a precision, three-terminal voltage reference delivering a fixed 1.2V output in a SOT-23-3 package. It features an initial accuracy of ±1% and a maximum temperature coefficient of 50ppm/°C. The device operates from a supply voltage range of 2.4V to 11V with a quiescent supply current of 70µA maximum. It provides line regulation of 400µV/V and load regulation of 1µV/µA.

Feature Summary

• Lowest-power 1.2V precision three-terminal voltage reference in a SOT23-3 package
• Supply current remains independent of input voltage across the operating temperature range
• Operates from a low supply voltage as low as 2.4V for battery-powered applications

Applications

• Battery-Powered Systems
• Portable and Hand-Held Equipment
• Data-Acquisition Systems
• Instrumentation and Process Control

Procurement Notes

Verify the specific suffix 'EUR' against the manufacturer's official documentation to confirm the exact temperature range and packaging specifications. Ensure compatibility with the required input voltage range of 2.4V to 11V and validate that the 70µA maximum supply current meets the power budget constraints of the target design.

Selection Notes

Select this component when minimizing power consumption is critical in 3V battery-powered equipment. It serves as a low-power alternative to two-terminal shunt references by eliminating the need for external series resistors. Consider its 1.2V output level and ±1% initial accuracy for applications requiring stable reference voltages without significant power overhead.

Part Context

The MAX6520 belongs to Maxim Integrated's family of ultra-low-power voltage references designed for portable electronics. It utilizes a bandgap reference architecture to achieve stability over temperature. The SOT-23-3 package allows for compact board layouts in space-constrained handheld devices and instrumentation systems where efficiency is paramount.
