LM4040C30IDBZR – TEXAS INSTRUMENTS

The Texas Instruments LM4040C30IDBZR is a 3.0V precision shunt voltage reference in a SOT-23-5 surface-mount package. This device offers a highly stable output voltage, specified at 3.0V ±0.5% initial tolerance over its operating temperature range of -40°C to +125°C. Its low temperature coefficient of ±20ppm/°C ensures minimal drift, crucial for applications demanding high accuracy. The LM4040C30IDBZR features a low output noise of typically 50µVrms, contributing to a clean reference voltage. It operates with a reverse breakdown voltage of -0.5V and a maximum input current of 10mA, allowing for flexibility in circuit design._x000D_

This shunt regulator is ideally suited for applications requiring a precise, stable voltage source, such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and operational amplifier (op-amp) bias circuits. Its small size and low power consumption make it suitable for portable and space-constrained designs. The inherent stability minimizes the need for external compensation networks, simplifying circuit design and reducing component count, thereby lowering costs and improving reliability compared to less precise alternatives. The SOT-23-5 package facilitates automated surface-mount assembly processes.
