MAX6138CEXR50+T

Overview

The MAX6138CEXR50+T is a precision, two-terminal shunt mode bandgap voltage reference with a fixed reverse breakdown voltage of 5.0V. It operates within a temperature range of -40°C to +85°C and features an initial accuracy of 0.5%. The device utilizes a subminiature 3-pin SC70 surface-mount package measuring 1.8mm x 1.8mm. It supports a wide operating current range from 60μA to 15mA and maintains stability without requiring external capacitors.

Feature Summary

• Ultra-small 3-pin SC70 package for space-critical applications
• Laser-trimmed resistors ensure precise initial accuracy
• Stable operation with any output capacitance without external stabilizing capacitors

Applications

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

Procurement Notes

Verify the specific suffix 'C' corresponds to the required 0.5% initial accuracy grade before procurement. Confirm that the '+T' designation matches the intended reel packaging format. Ensure the selected component meets the specified RoHS compliance requirements for the target assembly process.

Selection Notes

Select this part when a compact footprint is required alongside stable shunt regulation. The 5.0V output suits systems needing a direct high-voltage reference. Verify that the application load current remains within the 60μA to 15mA operational window to maintain specified performance levels.

Part Context

This component belongs to the MAX6138 family of precision shunt voltage references. The family offers multiple fixed reverse breakdown voltages including 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. All variants share the same ultra-small SC70 package and low dynamic impedance characteristics.

Replacement Considerations

The LM4040/LM4050 series are noted as comparable devices in larger packages. Direct pin-compatible replacements within the same package size require matching the exact voltage and accuracy grade.
