MAX6037BAUK12-T

Overview

The MAX6037BAUK12-T is a low-dropout, micropower voltage reference from the MAX6037 family. It provides a fixed output voltage of 1.25V with an initial accuracy of ±0.2% (max) and a maximum temperature coefficient of 25ppm/°C. The device operates from a 2.5V to 5.5V supply, consuming a maximum quiescent current of 275µA. It features shutdown functionality with active-low control, drawing less than 500nA in shutdown mode. The output can source and sink 5mA of load current while remaining stable driving loads between 0.02µF and 1µF. The component is specified over the automotive temperature range of -40°C to +125°C.

Feature Summary

• Offers fixed 1.25V output with high initial accuracy and low temperature drift
• Includes active-low shutdown capability for significant power reduction
• Capable of sourcing and sinking 5mA load current
• Operates within a wide input voltage range of 2.5V to 5.5V

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when reviewing distributor listings. Confirm the 'B' grade designation aligns with the required ±0.2% accuracy and 25ppm/°C temperature coefficient specifications. Ensure the 1.25V fixed output variant matches the design requirement rather than the adjustable version. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component for battery-powered applications requiring low quiescent current and precise voltage stability. The low dropout voltage makes it suitable for systems operating near minimum supply thresholds. Consider the 5-pin SOT23 package constraints for PCB layout. Verify that the 5mA output current capability meets the reference load requirements without external buffering.

Part Context

This part belongs to the MAX6037 family of micropower voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family includes both fixed and adjustable output options ranging from 1.184V to 5V. These series-mode references are designed for high precision in miniature packages, targeting automotive and industrial environments where space and power efficiency are critical.

Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify pin compatibility and electrical specifications before substitution.
