V62/11615-01XE

Overview

The V62/11615-01XE is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy tolerance of 0.65% and a maximum temperature coefficient of 100 ppm/°C. The device operates over an extended temperature range from -55°C to +125°C and supports cathode currents ranging from 45 μA typical to 15 mA maximum. It features low output noise of 35 μVRMS typical and maintains stability with all capacitive loads without requiring external compensation capacitors.

Feature Summary

• Provides a stable 2.5 V reference with tight initial accuracy and low temperature drift
• Operates reliably across military-grade temperature ranges (-55°C to +125°C)
• Capable of driving any capacitive load without the need for output bypass capacitors

Applications

• Data-acquisition systems
• Power supplies and power-supply monitors
• Instrumentation and test equipment
• Process controls
• Precision audio applications

Procurement Notes

Verify that the component matches the specific LM4040-EP enhanced product designation. Confirm the package type is SOT-23 (DBZ) and check the status as NRND (Not Recommended for New Designs). Ensure the ordering suffix aligns with the required reel quantity of 250 units. Validate RoHS compliance and lead finish specifications against project requirements before finalizing procurement.

Selection Notes

Select this component when a high-precision, low-noise voltage reference is required for space-constrained designs. The SOT-23-3 package offers a compact footprint suitable for portable and battery-powered equipment. Consider the minimum operating current of 45 μA when designing biasing circuits to ensure proper regulation under light load conditions.

Part Context

This part number represents the military-enhanced version of the LM4040 series, specifically the LM4040C25 variant. It is designed to support defense, aerospace, and medical applications through controlled baseline manufacturing. The device utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to achieve its specified tight tolerances.
