MAX6138BEXR12+T

Overview

The MAX6138BEXR12+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 1.2205V with an initial accuracy of 0.2%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 25ppm/°C. It supports a wide operating current range from 60μA to 15mA and utilizes a subminiature 3-pin SC70 surface-mount package.

Feature Summary

Ultra-small 3-pin SC70 surface-mount package
Laser-trimmed resistors for precise initial accuracy
Low dynamic impedance ensuring stable voltage across currents
Capable of driving capacitive loads without external stabilizing capacitors

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process control

Procurement Notes

Verify the specific suffix 'B' indicates the 0.2% initial accuracy grade when sourcing this component. Confirm that the '+T' designation corresponds to the reel packaging format required for your assembly line. Ensure the ordering part number matches the exact 1.2205V output specification before procurement to avoid functional mismatches in precision circuits.

Selection Notes

Select this component when space constraints require a smaller footprint than standard SOT-23 packages while maintaining high precision. It is suitable for applications needing a stable reference voltage over a wide current range without requiring external compensation components. Consider the 0.2% accuracy grade if tighter tolerances are unnecessary compared to the 0.1% option.

Part Context

This device belongs to the MAX6138 family of shunt voltage references, which offers multiple fixed reverse breakdown voltages including 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. All variants share the same ultra-small SC70 package and general electrical characteristics, differing primarily in their nominal output voltage and available accuracy grades.
