MAX6037AAUK25+T

Overview

The MAX6037AAUK25+T is a low-dropout, micropower voltage reference providing a fixed 2.5V output with ±0.2% initial accuracy and a maximum temperature coefficient of 25ppm/°C. It operates from a 2.5V to 5.5V supply, consuming 275µA (max) quiescent current. The device features an active-low shutdown mode reducing current to under 500nA, supports 5mA source/sink loads, and maintains 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 with ±0.2% initial accuracy and low temperature drift
• Capable of sourcing and sinking up to 5mA load current

Applications

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

Procurement Notes

Verify the specific suffix 'UK25' confirms the 2.5V fixed output variant. Confirm the 'A' grade designation matches the required ±0.2% accuracy and 25ppm/°C temperature coefficient specifications. Ensure the '+T' tape-and-reel packaging aligns with assembly requirements. Cross-reference the manufacturer's latest documentation for any updates to the automotive temperature range or pin configuration.

Selection Notes

Select this component when a stable 2.5V reference is required in space-constrained designs utilizing the SOT-23-5 package. It is appropriate for systems needing precise voltage regulation with minimal static power draw. Consider the 275µA quiescent current limit and the 5mA drive capability against the application's dynamic load demands.

Part Context

This part belongs to the MAX6037 family of low-power references manufactured by Analog Devices Inc./Maxim Integrated. The family includes adjustable versions and other fixed voltages such as 1.25V, 2.048V, 3.0V, and 3.3V. All variants share the same miniature 5-pin SOT-23 footprint and operate over the -40°C to +125°C automotive temperature range.

Replacement Considerations

Other MAX6037 variants with different output voltages or grades may serve as functional substitutes if the electrical parameters meet system requirements. Verify pin compatibility and thermal characteristics before substitution.
