MAX6129BEUK30-T

Overview

The MAX6129BEUK30-T is an ultra-low-power series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3 V with an initial accuracy of 1%. The device operates within an input voltage range up to 13 V and supports a maximum shunt current of 4 mA. It features a temperature coefficient of 100 PPM/C and functions reliably across a temperature range from -40 C to +85 C. The component is housed in a compact SOT-23-5 surface-mount package, designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

• Ultra-low-power series voltage reference design
• Fixed 3 V output with 1% initial accuracy
• Operates over extended industrial temperature range

Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition circuits

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations such as +T or specific reel/cut-tape designations may exist. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the ordering information matches the required package type and temperature grade for your specific application requirements before finalizing procurement.

Selection Notes

Select this component when a low-cost, fixed 3 V reference is needed with moderate precision. The 100 PPM/C temperature coefficient suits applications where high stability is not critical. Compare against higher-precision alternatives like the MAX6029 if tighter accuracy or lower drift is required. Ensure the input voltage remains within the specified maximum limits during operation.

Part Context

This part belongs to the MAX6129B series of voltage references. It shares the same family characteristics but differs in output voltage and accuracy specifications from other variants like the MAX6129E. The series is designed for general-purpose voltage referencing in portable electronics.
