ZXRE125EN8TA

Overview

The ZXRE125EN8TA is a bandgap voltage reference IC providing a fixed 1.22V output with ±2% initial accuracy. It operates within a current range of 4µA to 20mA and features a typical temperature coefficient of 75ppm/°C. The device utilizes an SOT-23 surface-mount package, measuring 3.04mm in length and 1.02mm in height. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Bandgap circuit architecture for precision micropower voltage referencing
• Unconditionally stable operation tolerant of capacitive loads
• Small outline SOT-23 package designed for space-saving applications

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix 'N8' against official Diodes Incorporated documentation, as standard datasheets list variants such as CFTA, DFTA, EFTA, and FFTA. Confirm whether this suffix denotes a distinct package type or tape-and-reel specification. Ensure compliance with RoHS3 standards and check for any product change notifications affecting availability.

Selection Notes

Select based on required tolerance levels, which range from 0.5% to 3%. Consider the 75ppm/°C temperature coefficient for the 2% variant when designing for thermal stability. Verify that the 4µA minimum operating current aligns with low-power system requirements and that the SOT-23 footprint fits the PCB layout constraints.

Part Context

This component belongs to the ZXRE125 series of micropower voltage references manufactured by Diodes Incorporated. The series provides a stable 1.22V reference in compact packages. It serves as a pin-for-pin compatible replacement for older ZRA124 and ZRA125 series devices, facilitating upgrades in existing designs requiring smaller footprints.

Replacement Considerations

The ZXRE125 series offers a direct pin-for-pin replacement for the ZRA124 and ZRA125 series voltage references.
