MAX6037BAUK33+T

Overview

The MAX6037BAUK33+T is a low-dropout, micropower voltage reference from the Maxim Integrated family. It provides a fixed 3.3V output with an initial accuracy of ±0.3% and a maximum temperature coefficient of 50ppm/°C. The device operates from a 2.5V to 5.5V supply, consuming a maximum quiescent current of 275µA. It features active-low shutdown functionality reducing current to under 500nA. The component supports sourcing and sinking up to 5mA of load current and maintains stability with capacitive loads ranging from 0.02µF to 1µF.

Feature Summary

• Active-low shutdown mode reduces quiescent current to less than 500nA for power conservation
• Low dropout voltage capability ensures stable regulation in low-voltage applications
• Capable of sourcing and sinking up to 5mA of load current
• Operates reliably across the automotive temperature range of -40°C to +125°C

Applications

• Medical equipment requiring precise voltage references
• Portable battery-powered devices needing low power consumption
• Wireless LAN systems utilizing stable reference voltages
• Precision regulators demanding high accuracy and low drift

Procurement Notes

Verify the complete part number including suffixes such as '+T' against official manufacturer documentation to ensure correct package type and tape-and-reel configuration. Confirm that the 'B' grade designation matches the required initial accuracy and temperature coefficient specifications for your specific design constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3V reference with moderate precision (±0.3%) is sufficient. Consider the B-grade specifications regarding temperature coefficient if operating in wide thermal environments. Ensure the input voltage remains within the 2.5V to 5.5V range and verify that the load requirements do not exceed the 5mA source/sink capability.
