ZXRE125FRSTOB

Overview

The ZXRE125FRSTOB is a precision micropower shunt voltage reference manufactured by Diodes Incorporated. It utilizes a bandgap circuit architecture to provide a stable output voltage of 1.22 V. The device features an initial accuracy of ±0.5% and operates within a temperature range of -40°C to +85°C. It supports a maximum shunt current of 20 mA with a minimum operating current of 8 µA. Packaged in a compact SOT-23-3 surface-mount format, it offers low noise performance suitable for sensitive analog applications.

Feature Summary

• Provides a fixed 1.22 V precision reference via bandgap technology
• Operates with micropower consumption starting at 8 µA
• Delivers high initial accuracy of ±0.5%
• Designed for compact surface-mount integration

Applications

• Portable battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'RSTOB' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and exact tolerance grades. Ensure compatibility with standard SOT-23 footprint designs during procurement planning.

Selection Notes

Select this component when a low-cost, small-footprint voltage reference is required for portable devices. The 1.22 V output is ideal for direct interfacing with ADCs in single-supply systems. Consider the ±0.5% initial accuracy for applications requiring moderate precision without complex calibration.

Part Context

This part belongs to the ZXRE125 series from Diodes Incorporated, which focuses on micropower voltage references. The series is designed for cost-sensitive applications where space is limited. The SOT-23 package allows for efficient PCB layout in consumer electronics and industrial control modules.

Replacement Considerations

Compatible substitutes include ZXRE125CFTA and ZXRE125EFTA from the same manufacturer family. Verify pinout compatibility and thermal characteristics before substitution.
