V62/04756-01XE

Overview

The V62/04756-01XE is a military-enhanced precision-programmable shunt reference from the TL1431-EP family, manufactured by Texas Instruments. It operates within a -55°C to +125°C temperature range and features an initial voltage tolerance of 0.4%. The device supports adjustable output voltages from approximately 2.5 V up to 36 V using two external resistors. Key electrical specifications include a maximum cathode current of 100 mA, a typical output impedance of 0.2 Ω, and a reference input current of 4 µA at full temperature range.

Feature Summary

• Certified to the Aerospace Qualified Electronic Component (AQEC) Standard for high-reliability environments
• Features active output circuitry providing sharp turn-on characteristics for precise regulation
• Maintains specified thermal stability across the extended military temperature range
• Offers controlled baseline manufacturing with single assembly, test, and fabrication sites

Applications

• Shunt regulators in power supply circuits
• Temperature-compensated comparators
• PWM converter references
• Photodiode reference drivers
