MAX6037CAUK41+T

Overview

The MAX6037CAUK41+T is a low-dropout, micropower voltage reference from the MAX6037 family. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.5% and a maximum temperature coefficient of 50ppm/°C. The device operates from a supply voltage range of 2.5V to 5.5V, consuming a maximum quiescent current of 275µA. It features active-low shutdown functionality that reduces supply current to less than 500nA. The output can source and sink up to 5mA of load current while maintaining stability with capacitive loads between 0.02µF and 1µF. It is housed in a 5-pin SOT-23 package and specified over the -40°C to +125°C automotive temperature range.

Feature Summary

• Active-low shutdown mode reduces quiescent current to less than 500nA for power conservation
• Low dropout voltage capability allows operation in low-voltage battery-powered applications
• Capable of sourcing and sinking up to 5mA of load current
• Stable driving capacitive loads ranging from 0.02µF to 1µF

Applications

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

Procurement Notes

Verify the specific suffix '41' confirms the 4.096V fixed output variant. Ensure the 'C' grade designation matches the required 0.5% initial accuracy and 50ppm/°C temperature coefficient specifications. Confirm the '+T' suffix indicates tape-and-reel packaging compatible with automated assembly processes. Cross-reference the manufacturer's latest documentation for any pinout or electrical characteristic updates.

Selection Notes

Select this component when a stable 4.096V reference is required in space-constrained designs utilizing the SOT-23-5 package. It is suitable for applications demanding low static current consumption and the ability to disable the reference via a digital control signal. Consider the 50ppm/°C drift if high precision across wide temperature ranges is critical compared to higher-grade alternatives.
