ZXRE125EFTA

Overview

The ZXRE125EFTA is a bandgap micropower voltage reference providing a fixed output of 1.22V with an initial tolerance of ±2%. It operates within a current range of 8µA to 20mA and features a typical temperature coefficient of 75ppm/°C. The device is housed in a surface-mount SOT-23 package, supports an operating temperature from -40°C to +85°C, and exhibits a wideband noise voltage of 60µVrms.

Feature Summary

• Bandgap circuit architecture designed for precision micropower applications
• Unconditionally stable operation with high capacitive load tolerance
• Space-saving small outline SOT-23 surface mount packaging

Applications

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

Procurement Notes

Verify component status before procurement as the E-line variant is officially obsolete and no longer available for sale. Confirm that the specific ordering suffix matches the required tolerance grade and package type. Ensure compliance with RoHS3 specifications and check for any product change notifications affecting manufacturing sources or assembly sites prior to finalizing orders.

Selection Notes

Select this component when a compact SOT-23 footprint is required for space-constrained designs. The ±2% tolerance suits general-purpose applications where tighter accuracy is not critical. Verify that the system can maintain the recommended operating current between 8µA and 20mA to ensure optimal performance and stability under varying load conditions.

Part Context

This part belongs to the ZXRE125 series of voltage references manufactured by Diodes Incorporated. It serves as a pin-for-pin compatible replacement for the ZRA124 and ZRA125 series. The series includes variants with different tolerance grades, including 0.5%, 1%, 2%, and 3% options, all utilizing the same SOT-23 package structure.

Replacement Considerations

The ZXRE125EFTA offers a direct pin-for-pin replacement for the ZRA124 and ZRA125 series voltage references.
