ZXRE1004ER

Overview

The ZXRE1004ER is a 1.22V bandgap shunt voltage reference in an E-Line (TO-92 style) package. It provides a fixed output with ±2% tolerance and operates within a current range of 8µA to 20mA. The device features a typical temperature coefficient of 20ppm/°C and supports unconditionally stable operation under capacitive loads. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Provides a precise 1.22V reference voltage suitable for portable applications
• Designed for ultra-low power consumption with a minimum knee current of 8µA
• Maintains stability when driving capacitive loads without oscillation
• Offers pin-for-pin compatibility with legacy REF1004 and LT1004 references

Applications

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

Procurement Notes

Verify the specific suffix against official documentation, as ordering codes determine tolerance and packaging. Confirm component status, as this series may be obsolete or restricted for new designs. Ensure compliance with RoHS3 and REACH regulations before procurement. Cross-reference datasheet revision dates to validate electrical characteristics.

Selection Notes

Select based on required tolerance levels, as tighter specifications require contacting marketing directly. Evaluate operating current requirements to ensure they remain within the 8µA to 20mA range for optimal performance. Consider thermal management needs relative to the specified operating temperature limits.

Part Context

This component belongs to the ZXRE1004 family of micro-power voltage references manufactured by Diodes Incorporated. The family includes SOT23 surface mount variants and E-Line through-hole equivalents designed to replace older industry standards like the LM185 and LM385 series.

Replacement Considerations

Officially documented pin-compatible alternatives include the REF1004, LT1004, LM185, and LM385 series.
