ZXRE1004DFTA

Overview

The ZXRE1004DFTA is a 1.22V bandgap voltage reference in an SOT23 package, designed for ultra-low current operation with a typical knee current of 4µA and a recommended operating range from 8µA to 20mA. It provides a 1% initial tolerance and maintains excellent stability under capacitive loads. The device features a typical temperature coefficient of 20ppm/°C over the -40°C to +85°C operating temperature range.

Feature Summary

• Ultra-low power consumption suitable for battery-powered applications
• Unconditionally stable performance even with high capacitive loads
• Compact SOT23 surface-mount footprint for space-constrained designs

Applications

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

Procurement Notes

Verify component status before procurement as this specific part number is marked obsolete and not recommended for new design. Confirm availability through authorized distributors or consider alternative replacement parts. Ensure compliance with RoHS and lead-free requirements specified in the datasheet notes.

Selection Notes

Select this component when low quiescent current and small physical size are critical constraints. The 1% tolerance meets standard precision requirements, while the wide operating current range ensures flexibility in circuit design. Verify that the application does not require tighter tolerances than the D-grade offers.

Part Context

This micro-power voltage reference serves as a direct pin-for-pin compatible alternative to legacy REF1004, LT1004, and LM185/385 series references. It replaces older technologies by offering superior space efficiency and lower power dissipation within the same SOT23 form factor.
