RC0431AMT

Overview

The RC0431AMT is a two-terminal adjustable precision voltage reference manufactured by Fairchild Semiconductor. It utilizes a trimmable bandgap architecture to provide stable reference performance. The device operates within a supply voltage range of 1.24 V to 12 V and delivers a maximum output current of 15 mA. It is housed in a compact SOT-23 surface-mount package with five terminals. The component supports an operating temperature range from -25 °C to 70 °C, ensuring reliability in commercial electronic applications requiring precise voltage regulation.

Feature Summary

• Provides a stable, adjustable reference voltage using a trimmable bandgap design
• Operates over a wide input voltage range up to 12 V
• Delivers high output current capability for driving load requirements
• Available in a small outline surface-mount package for space-constrained designs

Applications

• Precision voltage regulation circuits
• Battery-powered equipment power management
• Portable instrumentation reference sources
• Data acquisition system voltage references

Procurement Notes

Verify the specific suffix 'AMT' against official Fairchild documentation to confirm the exact pinout configuration and tape-and-reel packaging specifications. Ensure that the procurement source provides valid RoHS compliance certificates matching the component's environmental standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a low-cost, adjustable voltage reference is required for commercial-grade applications. The SOT-23 package is suitable for automated surface-mount assembly processes. Consider the 15 mA output current limit when designing load circuits. Verify that the operating temperature range meets the environmental conditions of the target application board.

Part Context

This component belongs to the family of two-terminal voltage references designed for cost-sensitive electronics. It serves as an alternative to fixed-bandgap references by allowing external resistor adjustment. The device integrates the reference core and pass element into a single semiconductor die, simplifying circuit topology compared to three-terminal regulator variants while maintaining comparable accuracy levels.
