ZXRE125ERSTZ

Overview

The ZXRE125ERSTZ is a bandgap circuit designed to achieve a precision micropower voltage reference of 1.22 volts. It operates within an operating temperature range of -40°C to 85°C and features a typical temperature coefficient of 75 ppm/°C. The device maintains excellent performance over an operating current range from 4 µA to 20 mA, with a minimum operating current of 4 µA and a recommended operating current of 20 mA. It provides a reverse breakdown voltage of 1.226 V at 2% tolerance.

Feature Summary

• High performance 1.220V reference
• Small outline SOT23 package
• Unconditionally stable

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation

Procurement Notes

Verify the specific ordering suffix for the ZXRE125ERSTZ against official Diodes Incorporated documentation to confirm availability status and exact electrical tolerances. Confirm that the component meets RoHS3 compliance requirements before procurement. Ensure the selected variant matches the required initial accuracy for the target application design.

Selection Notes

Select this component when space-saving surface mount packaging is required alongside precise voltage referencing. Consider the 2% tolerance and 75 ppm/°C temperature coefficient for applications where these parameters align with system stability requirements. Evaluate the 4 µA knee current for low-power battery-operated designs.
