MAX6037AAUK12+T

Overview

The MAX6037AAUK12+T is a low-dropout, micropower voltage reference from the Maxim Integrated family. It provides a fixed output voltage of 1.25V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 2.5V to 5.5V and features a shutdown mode that reduces quiescent current to less than 500nA. It can source and sink up to 5mA of load current while maintaining stability with capacitive loads between 0.02µF and 1µF.

Feature Summary

• Integrated active-low shutdown functionality for ultra-low power consumption
• Low dropout voltage capability suitable for battery-powered applications
• High precision A-grade performance with tight initial accuracy and temperature coefficient
• Capable of sourcing and sinking significant load currents in a miniature package

Applications

• Medical Equipment
• Portable Equipment
• Wireless LAN Systems
• Precision Regulators

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '+T' designation ensures compliance with lead-free manufacturing standards as specified by the manufacturer. Ensure the component matches the exact part number to guarantee the A-grade electrical characteristics and automotive temperature range specifications are met.

Selection Notes

Select this component for designs requiring high precision at 1.25V with minimal power dissipation. The A-grade specification is critical for applications demanding strict tolerance limits. Consider the SOT23-5 footprint for space-constrained layouts. Evaluate the shutdown pin requirements if power management during idle states is necessary for the system architecture.

Part Context

This device belongs to the MAX6037 family of series-mode voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family includes various fixed voltage options and adjustable versions. The AAUK12 variant specifically denotes the 1.25V output with A-grade accuracy metrics, distinguishing it from B and C grades which offer lower precision but potentially different cost structures.

Replacement Considerations

Substitutes within the same family include MAX6037BAUK12+T and MAX6037CAUK12+T. These alternatives provide the same 1.25V output and package but feature relaxed accuracy and temperature coefficient specifications compared to the A-grade version.
