MAX6037BAUKADJ+T

Overview

The MAX6037BAUKADJ+T is a low-power, adjustable series voltage reference in a 5-pin SOT-23 package. It provides an output range of 1.184V to 5V using external resistors. Key electrical parameters include a maximum initial accuracy of ±0.3%, a temperature coefficient of 50ppm/°C, and a quiescent current of 275µA (max). The device supports a supply voltage from 2.5V to 5.5V, offers 5mA source/sink capability, and features an active-low shutdown mode with current below 500nA.

Feature Summary

• Adjustable output voltage configuration via external resistor divider
• Active-low shutdown functionality for ultra-low power consumption
• Low dropout voltage operation suitable for battery-powered systems
• Automotive-grade specification over extended temperature range

Applications

• Medical equipment requiring stable reference voltages
• Portable instrumentation and handheld devices
• Wireless LAN infrastructure components
• Precision regulator circuits

Procurement Notes

Verify the specific suffix 'BAUKADJ' corresponds to the B-grade accuracy and adjustable variant. Confirm RoHS compliance status (+T indicates tape and reel packaging). Check manufacturer lifecycle status as availability may be limited or subject to factory special orders. Ensure the ordering code matches the required automotive temperature rating and package type.

Selection Notes

Select this component when an adjustable reference voltage between 1.184V and 5V is required within a compact SOT-23 footprint. Choose the B-grade version if ±0.3% initial accuracy and 50ppm/°C temperature coefficient meet design specifications. Consider the shutdown feature for applications requiring significant power savings during idle periods.

Part Context

This part belongs to the MAX6037 family of micropower voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family includes fixed-output variants and other accuracy grades (A and C). The MAX6037 series is designed for low-voltage, battery-operated applications where space and power efficiency are critical constraints.

Replacement Considerations

Other members of the MAX6037 family, such as MAX6037AAUKADJ+T or MAX6037CAUKADJ+T, share the same pinout and package but differ in accuracy and temperature coefficient specifications.
