FAN4050BIS325X

Overview

The FAN4050BIS325X is a fixed voltage reference IC manufactured by Fairchild Semiconductor, designed for low-power electronic circuits. It provides a stable 2.5V output with a tolerance of ±0.2% and supports an output current of 15 mA. The device features a low temperature coefficient and operates in a surface-mount SOT-23-3 package. It is optimized for precision applications requiring high accuracy and stability in power management systems.

Feature Summary

• Fixed 2.5V output voltage for precision reference applications
• High accuracy with ±0.2% initial tolerance
• Low noise performance suitable for sensitive analog circuits
• Compact SOT-23-3 surface-mount package for space-constrained designs

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Battery-powered devices needing low quiescent current
• Medical instrumentation with strict accuracy requirements

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or ON Semiconductor post-acquisition. Confirm the SOT-23-3 package type and 2.5V fixed output specification match project requirements. Ensure compliance with RoHS directives if applicable. Check datasheet for operating temperature range and load regulation details before integration.

Selection Notes

Select this component when a precise, low-noise 2.5V reference is needed in a small footprint. Consider its ±0.2% tolerance and 15 mA drive capability for driving ADCs or comparators. Evaluate thermal performance if operating near temperature extremes. Compare with other fixed references if higher current or different voltage levels are required.

Part Context

Fairchild Semiconductor was acquired by ON Semiconductor in September 2016. The FAN4050 series belongs to the company's portfolio of power management voltage references. This specific part is designed for applications demanding high stability and low power consumption in compact electronic systems.

Replacement Considerations

Check for direct pin-compatible alternatives from ON Semiconductor or other manufacturers offering 2.5V references in SOT-23-3 packages. Verify electrical parameters such as tolerance, temperature coefficient, and output current to ensure functional equivalence without circuit redesign.
