LM4040A30IDBZR General Description

The LM4040A30IDBZR is a precision voltage reference IC (integrated circuit) manufactured by Texas Instruments. It is a 3.0V fixed voltage reference that provides a stable and accurate reference voltage for various electronic circuits. The device operates with a very low dynamic impedance of 0.2Ω, ensuring good stability and minimizing voltage variations over temperature changes. It has a temperature coefficient of 75ppm/°C, meaning that the output voltage remains relatively constant over a wide range of temperatures.The LM4040A30IDBZR is housed in a small SOT-23 surface-mount package, making it suitable for space-constrained applications. It can operate with a supply voltage range of 4V to 30V, with a maximum operating current of 15mA. This voltage reference IC is commonly used in precision measurement equipment, data acquisition systems, and other analog circuits where a stable voltage reference is required.
