MAX6037AAUKADJ+T

Overview

The MAX6037AAUKADJ+T is a low-power, adjustable series-mode voltage reference in a 5-pin SOT-23 package. It provides an output voltage range of 1.184V to 5V using an external resistive divider. The device features a maximum initial accuracy of ±0.2% and a temperature coefficient of 25ppm/°C. It operates from a supply voltage of 2.5V to 5.5V with a maximum quiescent current of 275µA. The part supports a shutdown mode with current below 500nA and can source or sink up to 5mA of load current.

Feature Summary

• Adjustable output voltage configuration via external resistor network
• Active-low shutdown functionality for ultra-low power consumption
• High precision with low temperature coefficient and tight initial accuracy
• Capable of sourcing and sinking significant load currents

Applications

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

Procurement Notes

Verify the specific suffix 'ADJ' confirms the adjustable variant rather than fixed voltage options. Ensure the 'AA' grade designation matches the required 0.2% accuracy and 25ppm/°C specifications. Confirm the '+T' tape-and-reel packaging aligns with assembly requirements. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when an adjustable reference voltage between 1.184V and 5V is required in a compact SOT-23 footprint. It is suitable for battery-powered designs due to low quiescent current and shutdown capability. Consider the 25ppm/°C drift if high thermal stability is critical. Verify that the external resistors used for adjustment have matching low temperature coefficients to maintain overall accuracy.

Part Context

This part belongs to the MAX6037 family of micropower voltage references manufactured by Analog Devices (Maxim Integrated). The family includes both fixed and adjustable versions with varying accuracy grades. The AA grade represents the highest precision tier within the adjustable lineup, offering superior stability compared to B or C grades.
