ZXRE1004EN8TA

Overview

The ZXRE1004EN8TA is a discontinued bandgap voltage reference circuit manufactured by Diodes Incorporated. It provides a fixed output of 1.22V with a tolerance of ±2%. The device operates within a current range of 8µA to 20mA and features a typical temperature coefficient of 20ppm/°C. It is housed in an SOT-23 surface-mount package.

Feature Summary

• Ultra-low power consumption with a typical knee current of 4µA
• High stability maintained across the full operating current range
• Unconditionally stable operation without external capacitors
• Pin-compatible alternative to legacy REF1004, LT1004, and LM185/385 series

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems
• A/D and D/A converters

Procurement Notes

This component is officially obsolete and not recommended for new designs. Verify availability through secondary market channels only. Confirm that the specific lot matches the required electrical characteristics, as production has ceased. Ensure compliance with RoHS standards if applicable to your environment.

Selection Notes

Select this part only for maintenance or replacement of existing hardware where the ZXRE1004 family was previously specified. For new projects, consider modern equivalents from the manufacturer's current portfolio. Evaluate thermal performance and space constraints associated with the SOT-23 package before implementation.

Part Context

The ZXRE1004 belongs to a family of micro-power voltage references designed for portable applications. It serves as a direct drop-in replacement for older industry-standard references like the LM185. The EN8TA suffix indicates a specific tape-and-reel packaging configuration for the SOT-23 variant.

Replacement Considerations

The datasheet explicitly recommends using the ZXRE125 as the replacement for this obsolete product. Verify pinout compatibility and electrical specifications against the ZXRE125 datasheet before substitution.
