The LM4040CIM3-5.0 is a precision shunt voltage reference from Quarktwin Technology Ltd., providing a fixed output voltage of 5.000V with an initial accuracy of ¬±0.5%. It operates within a wide temperature range of -40¬8C to +85¬8C and is housed in a compact SOT-23-3 package. The device supports a shunt current range of 60¬µA to 15mA and features a low dynamic impedance, ensuring stable voltage output across varying conditions. With a temperature coefficient of 100ppm/¬8C and low output noise of 28¬µVRMS (10Hz to 10kHz), it is suitable for applications requiring high precision and reliability, such as portable and battery-powered devices. The LM4040CIM3-5.0 does not require external capacitors for stability, making it easy to integrate into designs.
