ZXRE125DR

Overview

The ZXRE125DR is a bandgap voltage reference IC providing a fixed 1.22V output with 1% initial tolerance. It operates within an input current range of 8µA to 20mA and features a typical temperature coefficient of 20ppm/°C. The device is housed in a surface-mount SOT-23 package, supports an operating temperature from -40°C to +85°C, and maintains stability under capacitive loads.

Feature Summary

• Provides a precise 1.22V micropower reference voltage
• Maintains excellent performance across the full operating current range
• Designed for unconditional stability with high capacitive load tolerance

Applications

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

Procurement Notes

Verify the specific suffix 'DR' against official Diodes Incorporated documentation, as standard datasheets list tape-and-reel variants such as DFTA. Confirm availability status, as E-line variants are obsolete. Ensure the component matches the required 1% tolerance grade and SOT-23 package dimensions before procurement.

Selection Notes

Select this component when space-saving SOT-23 packaging is required alongside precision voltage referencing. It serves as a pin-compatible replacement for ZRA124 and ZRA125 series references. Consider the 20ppm/°C temperature coefficient and low knee current for battery-powered or portable applications requiring stable reference voltages.

Part Context

The ZXRE125 belongs to the ZXRE125 series of micro-power voltage references manufactured by Diodes Incorporated. This series utilizes bandgap circuitry to deliver a stable 1.22V output. The product line includes various tolerance grades (0.5%, 1%, 2%, 3%) packaged in small outline SOT-23 cases suitable for automated insertion.

Replacement Considerations

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