LM4040C30FTA DIODES Voltage Reference

The LM4040C30FTA from Diodes Incorporated is a precision fixed 3.0V shunt voltage reference, ideal for space-constrained, cost-sensitive designs. For selection, it combines a tight ±0.5% initial accuracy with excellent stability, featuring a 100ppm/°C temperature coefficient. Operating from a minimal 70µA cathode current, it's optimized for low-power circuits and can source up to 15mA with 35µVrms low wideband noise. As a two-terminal shunt, it functions like a Zener diode, requiring only one external resistor, which simplifies design and saves PCB area. In application, it excels in providing a stable reference for ADCs/DACs in portable medical instruments, sensor calibration circuits in industrial controls, and precise power supply monitoring in telecom equipment. Its wide -40°C to +125°C range and SOT-23 package suit harsh environment data loggers, automotive diagnostics, and battery management systems. It ensures reliable threshold detection in comparators and precision current limiting. In stock at HL Electronics – request a quote for fast delivery.
