ZXRE125FFTA

Overview

The ZXRE125FFTA is a micropower shunt voltage reference from Diodes Incorporated, providing a fixed output of 1.22V with an initial accuracy tolerance of ±3%. 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 compact SOT-23 surface-mount package and maintains stability under capacitive loads.

Feature Summary

• Provides a precise 1.22V bandgap reference voltage
• Operates efficiently across a wide current range from 8µA to 20mA
• Designed for unconditional stability with high capacitive load tolerance
• Utilizes a space-saving SOT-23 surface mount package

Applications

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

Procurement Notes

Verify the specific suffix 'FF' confirms the required 3% tolerance level before procurement. Ensure the ordering code matches the exact reel specifications. Confirm compliance with RoHS3 standards as indicated in the datasheet documentation.

Selection Notes

Select this component when a low-cost, small-footprint voltage reference is needed. The 3% tolerance suits general applications where tighter precision is not critical. Verify that the operating current remains within the specified 8µA to 20mA range for optimal performance.

Part Context

This part belongs to the ZXRE125 series of micropower voltage references. It serves as a pin-for-pin compatible replacement for the ZRA124 and ZRA125 series. The series offers various tolerance grades including 0.5%, 1%, 2%, and 3% options.

Replacement Considerations

The ZXRE125FFTA is documented as a direct pin-for-pin replacement for the ZRA124 and ZRA125 series voltage references.
