ZXRE125ER

Overview

The ZXRE125ER is a bandgap circuit designed to achieve a precision micropower voltage reference of 1.22 volts. It operates within an operating current range of 8µA to 20mA and features a typical temperature coefficient of 20ppm/°C. The device provides a 2% tolerance variant with a maximum reverse breakdown voltage of 1.244V at 25°C. It is housed in a small outline SOT23 surface mount package, which is suitable for space-saving applications.

Feature Summary

• Bandgap circuit architecture providing a fixed 1.22-volt reference
• Unconditionally stable operation with high capacitive load tolerance
• Micropower design maintaining performance across the 8µA to 20mA operating current range

Applications

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

Procurement Notes

Verify component status before procurement as E-line variants are obsolete. Confirm exact ordering suffixes against official documentation to ensure correct tolerance grades. Check datasheet revisions for updates on availability and manufacturing changes prior to finalizing supply chain decisions.

Selection Notes

Select this component for designs requiring a compact, low-power voltage reference. The SOT23 package is ideal for space-constrained layouts. Ensure the required tolerance aligns with the specific letter code, as the standard series offers multiple accuracy grades for different precision requirements.

Part Context

This part belongs to the ZXRE125 family of micropower voltage references manufactured by Diodes Incorporated. The series includes various tolerance options packaged in the SOT23 form factor. These devices serve as pin-compatible replacements for older ZRA124 and ZRA125 series references.

Replacement Considerations

The ZXRE125 series serves as a pin-for-pin compatible replacement for the ZRA124 and ZRA125 series of voltage references.
