RS431AYSF3

Overview

The RS431AYSF3 is an adjustable shunt voltage reference integrated circuit manufactured by Runic Technology. It provides a programmable output voltage ranging from 2.5V to 36V with a standard tolerance of ±0.5%. The device operates within a temperature range of -40°C to 125°C and features a typical temperature coefficient of 50ppm/°C. It supports a cathode current of 500 µA and delivers an output current up to 100 mA. Packaged in a surface-mount SOT-23-3 (TO-236-3, SC-59) housing, it is RoHS3 compliant and classified under EAR99.

Feature Summary

Adjustable output voltage capability spanning 2.5V to 36V for flexible circuit design
High precision performance with a standard ±0.5% tolerance
Robust thermal stability across industrial temperature ranges

Applications

Precision voltage regulation in power supply circuits
Reference voltage source for analog-to-digital converters
Portable equipment requiring stable voltage references

Procurement Notes

Verify the specific suffix 'SF3' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement channel sources genuine Runic Technology components to maintain the specified ±0.5% tolerance and thermal performance standards.

Selection Notes

Select this component when a low-cost, high-precision adjustable reference is required in a compact SOT-23-3 package. It is suitable for applications needing a stable 2.5V to 36V output with minimal temperature drift. Consider the 500 µA cathode current requirement for biasing conditions during circuit design.

Part Context

This part belongs to the RS431 series of shunt voltage references produced by Runic Technology. It serves as a general-purpose voltage reference solution for consumer electronics and industrial control systems. The device integrates a bandgap reference and error amplifier to provide accurate voltage regulation in a small footprint.
