MAX6037BAUK30+T

Overview

The MAX6037BAUK30+T is a low-dropout, micropower series voltage reference manufactured by Analog Devices / Maxim Integrated. It provides a fixed output voltage of 3.0V with an initial accuracy of ±0.3% 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 reducing current to less than 500nA. The component supports sourcing and sinking up to 5mA of load current and is specified over the automotive temperature range of -40°C to +125°C in a 5-pin SOT-23 package.

Feature Summary

• Capable of sourcing and sinking up to 5mA of load current
• Automotive-grade specification covering extended temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the 0.3% accuracy grade and 'K30' denotes the 3.0V fixed output during procurement. Confirm the '+T' suffix corresponds to tape-and-reel packaging requirements. Ensure the component meets RoHS compliance standards as indicated by the '+' designation. Cross-reference the manufacturer part number with authorized distributors to confirm availability status.

Selection Notes

Select this component when a fixed 3.0V reference with moderate precision (±0.3%) is required. It is suitable for designs needing shutdown control to minimize standby power consumption. Consider the 50ppm/°C temperature coefficient against stricter A-grade alternatives if higher stability is needed. Ensure the input voltage remains within the 2.5V to 5.5V range for proper operation.

Part Context

This part belongs to the MAX6037 family of low-power voltage references. The family includes adjustable versions and other fixed voltage options such as 1.25V, 2.048V, 2.5V, 3.3V, and 4.096V. Variants are available in different accuracy grades, including A-grade (±0.2%, 25ppm/°C) and C-grade (±0.5%). All variants share the same SOT-23-5 package and core architecture.

Replacement Considerations

MAX6037AAUK30+T offers higher precision with 0.2% accuracy and 25ppm/°C tempco. MAX6037CAUK30+T provides lower cost with 0.5% accuracy and 50ppm/°C tempco. MAX6037BAUKADJ+T is the adjustable version of the same B-grade family.
