TL4050A50IDCKR

Overview

The TL4050A50IDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 30 PPM/C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and is housed in a SC-70-5 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances for sensitive measurement circuits.
• Optimized for low power consumption through micropower design suitable for battery-operated systems.
• Ensures stable performance across wide industrial temperature ranges with low thermal drift characteristics.

Applications

• Portable instrumentation requiring precise analog-to-digital conversion references
• Battery-powered measurement devices needing long-term stability
• Industrial process control systems utilizing shunt regulator topologies

Procurement Notes

Verify the specific suffix IDCKR against official datasheets to confirm the SC-70-5 package and tape-and-reel delivery format. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified by the manufacturer. Confirm availability status as distribution channels may vary for this specific part number variant.

Selection Notes

Select this component when a 5 V reference with 0.1% accuracy and 30 PPM/C drift is required in a compact SC-70-5 footprint. Consider the 15 mA maximum shunt current limit for load driving capabilities. Evaluate the -40°C to +125°C operating range against environmental conditions to ensure reliable operation without derating.
