REF3230AIDBVT

REF3230AIDBVT Description

The REF3230AIDBVT from Texas Instruments is a high-precision, low-power 3V fixed-output series voltage reference designed for applications requiring stable voltage regulation. With a ±0.2% initial accuracy and a 20ppm/°C temperature coefficient, this IC delivers exceptional stability across industrial temperature ranges. Operating from a 3.05V to 5.5V input range, it consumes only 135µA supply current, making it ideal for battery-powered and energy-sensitive systems. Packaged in a SOT23-6 form factor with Tape & Reel (TR) for automated assembly, it combines compactness with ease of integration.

REF3230AIDBVT Features

• Ultra-Low Noise (57µVrms, 10Hz–10kHz): Ensures clean reference voltage for precision analog circuits.
• Low Dropout (50mV): Maintains regulation even with input voltages close to the output.
• 10mA Output Current: Supports direct driving of moderate loads without buffering.
• RoHS3 & REACH Compliant: Meets environmental and safety standards.
• Not for New Designs: Suitable for legacy systems but not recommended for new developments.

REF3230AIDBVT Applications

• Data Acquisition Systems: Provides stable references for ADCs/DACs in industrial sensors.
• Portable Medical Devices: Low power and high accuracy suit glucose meters and wearables.
• Automotive Electronics: Reliable performance in infotainment and control modules.
• Energy-Harvesting Systems: Minimal quiescent current extends battery life in IoT nodes.

Conclusion of REF3230AIDBVT

The REF3230AIDBVT excels in precision voltage referencing with its low noise, low dropout, and tight tolerance. While marked as Not for New Designs, it remains a robust choice for maintaining or upgrading existing systems requiring 3V references with minimal power overhead. Its balance of performance and compact packaging makes it a versatile solution for industrial, medical, and automotive applications demanding reliability under varying conditions.
