IC VREF SHUNT 0.5% SOT23-3

Manufacturer: Texas Instruments

Categories: Voltage Reference

Quality Control: Learn More

Texas Instruments LM4040C20QDBZRG4 is a fixed shunt voltage reference with a precise 2.048V output and a tight ±0.5% tolerance. This component is designed for applications requiring stable voltage references, operating with a cathode current range from 80 µA up to 15 mA. The SOT-23-3 package (TO-236-3, SC-59) facilitates surface-mount integration. Key performance characteristics include a temperature coefficient of 100ppm/°C and noise performance of 35µVrms from 10Hz to 10kHz. This device is suitable for use in automotive, industrial, and consumer electronics sectors where reliable voltage regulation is critical. The component is supplied in Tape & Reel (TR) packaging for automated assembly processes.
