MAX6037CAUK25+T

Overview

The MAX6037CAUK25+T is a low-dropout, micropower voltage reference from the MAX6037 family. It provides a fixed output voltage of 2.5V 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 and consumes a maximum quiescent current of 275µA. It features active-low shutdown functionality that reduces supply current to less than 500nA. The component can source and sink up to 5mA of load current and maintains stability with capacitive loads between 0.02µF and 1µF. It is housed in a 5-pin SOT-23 package and is specified over the automotive temperature range of -40°C to +125°C.

Feature Summary

• Active-low shutdown mode reduces quiescent current to less than 500nA for battery-powered applications
• Low dropout voltage capability allows operation with minimal input-to-output differential
• Capable of sourcing and sinking up to 5mA of load current while maintaining regulation
• Operates reliably across the full automotive temperature range of -40°C to +125°C

Applications

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

Procurement Notes

Verify the specific suffix '25' confirms the fixed 2.5V output configuration. Confirm the 'C' grade indicates the 0.5% initial accuracy and 50ppm/°C temperature coefficient specifications. Ensure the '+T' designation matches the required tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this part when a stable 2.5V reference is required in space-constrained designs utilizing the SOT-23-5 package. It is suitable for applications demanding low power consumption and the ability to drive moderate load currents. Consider the thermal hysteresis and long-term stability parameters if high precision is maintained over wide temperature cycles.

Part Context

This component belongs to the MAX6037 family of low-power voltage references manufactured by Analog Devices / Maxim Integrated. The family includes various fixed voltage options and an adjustable version, all sharing similar low-dropout characteristics and shutdown capabilities within the same miniature package form factor.

Replacement Considerations

Other members of the MAX6037 family such as MAX6037BAUK25+T or MAX6037AAUK25+T offer different accuracy grades. Verify pin compatibility and electrical specifications before substituting.
