REF02AU/2K5

Overview

The REF02AU/2K5 is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 8 V to 40 V and draws a maximum supply current of 1.4 mA. It features a temperature coefficient of 15 ppm/°C and supports a maximum load current of 21 mA. The component is housed in an 8-SOIC surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure that the selected variant matches the required packaging format and moisture sensitivity level for your assembly process. Cross-reference the part number with the latest datasheet revisions to account for any design or material changes.

Selection Notes

Select this component when a stable 5 V reference is required with low drift characteristics. Consider the 15 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 21 mA output current capability against the load requirements. Verify that the 8-SOIC package fits the available board space and manufacturing constraints.
