MAX6129AEUK30-T

Overview

The MAX6129AEUK30-T is an ultra-low-power series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3V with an initial accuracy of ±0.4%. The device operates within a supply voltage range of 3.2V to 12.6V and draws a maximum supply current of 6.75µA. It features a temperature coefficient of 40ppm/°C and supports up to 4mA source current. The component is housed in a compact SOT-23-5 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• High precision with 0.4% initial accuracy and low drift
• Compact five-pin SOT-23 surface-mount package design

Applications

• Battery-powered portable instrumentation
• Precision data acquisition systems
• Handheld measurement devices

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as some variants may differ. Check for End-of-Life (EOL) notifications or obsolescence warnings from the manufacturer. Ensure the sourcing channel provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this part when a stable 3V reference is required with minimal quiescent current draw. The 0.4% accuracy class is appropriate for high-precision applications where tighter tolerances are necessary. Consider the SOT-23-5 footprint constraints during PCB layout planning. Evaluate the 40ppm/°C temperature coefficient against environmental thermal variations.

Part Context

This component belongs to the MAX6129 family of micropower, low-dropout bandgap voltage references. The series combines ultra-low supply current with low drift characteristics. Other variants in the family offer different output voltages such as 3.3V, 4.096V, and 5V, maintaining similar performance profiles and package options.
