RC0431AST

Overview

The RC0431AST is a low-voltage, three-terminal adjustable precision voltage reference regulator manufactured by Fairchild Semiconductor. It functions as a shunt voltage reference with an output voltage range from 1.24V to 12V. The device features excellent thermal stability over the standard commercial operating temperature range and offers a typical current capability of 15mA. Packaged in a compact SOT-753 (SC-74A) surface-mount case, it integrates a bandgap reference core for accurate regulation.

Feature Summary

Three-terminal adjustable precision voltage reference design
Excellent thermal stability across commercial temperature ranges
Compact SOT-753 surface-mount packaging

Applications

Low-voltage power supply regulation
Precision voltage reference circuits
Battery-powered equipment monitoring

Procurement Notes

Verify the manufacturer status, as Fairchild Semiconductor's semiconductor division was acquired by ON Semiconductor. Confirm whether the specific RC0431AST units are sourced from original Fairchild inventory or subsequent ON Semiconductor production runs. Ensure the package marking matches the SOT-753 specification and validate RoHS compliance documentation for the specific batch.

Selection Notes

Select this component when a low-cost, adjustable shunt regulator is required for space-constrained designs. The SOT-753 package suits applications needing minimal board area. Consider the 15mA current limit and 1.24V to 12V output range against circuit requirements. Verify thermal performance needs against the commercial grade specifications provided in the datasheet.

Part Context

The RC0431AST belongs to the 431 family of programmable shunt regulators, widely used as voltage references and simple linear regulators. This specific variant utilizes the SOT-753 package, offering a smaller footprint compared to traditional TO-92 or DIP packages. It serves as a cost-effective solution for basic voltage regulation tasks in consumer electronics and industrial control systems.

Replacement Considerations

Direct substitutes include LM431AIMX/NOPB and TL431 variants in compatible SOT-753 or SC-74A packages. Verify pinout compatibility and electrical parameters such as reference voltage tolerance and dynamic impedance before substitution.
