MAX6037AAUK12-T

Overview

The MAX6037AAUK12-T is a low-power, fixed-output voltage reference from the Maxim Integrated MAX6037 family. It provides a stable 1.25V output with an initial accuracy of ±0.2% and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 2.5V to 5.5V and features a shutdown mode with current consumption below 500nA. It supports sourcing and sinking up to 5mA of load current while maintaining stability with capacitive loads between 0.02µF and 1µF. Designed for automotive applications, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Offers fixed output voltage options including 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, and 4.096V.
• Features active-low shutdown functionality with minimal quiescent current consumption.
• Provides low dropout voltage capability suitable for battery-powered systems.
• Ensures high precision with low temperature coefficient and tight initial accuracy.

Applications

• Medical equipment
• Portable electronic devices
• Wireless LAN systems
• Precision regulators

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'AA' designation corresponds to the required A-grade specifications for accuracy and temperature coefficient. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any lead-free soldering constraints associated with the SOT-23-5 package.

Selection Notes

Select this part when a fixed 1.25V reference is required in a miniature SOT-23-5 package. It is suitable for designs needing low power consumption and high precision under varying temperatures. Consider the MAX6037ADJ variant if adjustable output voltages are necessary instead of fixed levels. Evaluate the 5mA source/sink capability against the load requirements of the target circuit.

Part Context

This component belongs to the MAX6037 family of micropower voltage references manufactured by Analog Devices (Maxim Integrated). The family includes both fixed and adjustable versions designed for low-dropout operation. These references are engineered for applications requiring high stability and low power dissipation in compact form factors.

Replacement Considerations

Compatible substitutes include other parts from the MAX6037 family with matching output voltages and package types. Verify pin compatibility and electrical specifications before substitution. Cross-reference tools can identify parametrically similar components from the same manufacturer.
