ZXRE125EFTC

Overview

The ZXRE125EFTC is a micropower shunt voltage reference providing a fixed output of 1.22V with ±2% tolerance. It operates within an 8µA to 20mA current range and features a typical temperature coefficient of 75ppm/°C. The device utilizes a SOT-23 surface-mount 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 SOT23 surface mount package

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
