REF5050IDGKR

Overview

The REF5050IDGKR is a precision series voltage reference manufactured by Texas Instruments, housed in an 8-VSSOP surface-mount package. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 5.2 V to 18 V and supports a maximum shunt current of 10 mA. Key electrical characteristics include a temperature coefficient of 3 ppm/°C and a supply current of approximately 800 µA to 1.2 mA. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with low drift characteristics suitable for sensitive analog circuits.
• Features low noise performance to maintain signal integrity in data acquisition systems.
• Utilizes a compact surface-mount package design to facilitate efficient PCB layout.

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation and measurement equipment
• Medical devices demanding accurate signal conditioning

Procurement Notes

Verify the specific suffix (DGKR) corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure compatibility with moisture sensitivity level requirements during storage and handling procedures prior to soldering.

Selection Notes

Select this component when a fixed 5 V output is required with tight tolerance specifications. Consider the thermal performance and package size constraints relative to the application environment. Evaluate the power consumption against system battery life requirements if applicable. Verify input voltage headroom remains within the specified operational limits.
