LM4040A1Z-5.0/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM4040A1Z-5.0/NOPB is a 5.0V shunt precision voltage reference in a SOT-23-5 (5-lead surface mount) package, featuring a lead-free, no-halogen (NOPB) finish. It provides a highly stable 5.0V output with a typical initial accuracy of ±0.5% and a temperature coefficient of ±20ppm/°C over its operating temperature range of -40°C to +125°C. The device operates with a minimum operating current of 500µA and a maximum of 10mA. Its low noise floor (typically <10µVrms) and low output impedance (typically 0.5Ω) make it ideal for applications requiring a clean, stable voltage reference._x000D_ _x000D_ The LM4040A1Z-5.0/NOPB's inherent precision eliminates the need for external trimming in many applications, simplifying circuit design and reducing component count. Common use cases include precision analog-to-digital converters (ADCs), instrumentation amplifiers, and voltage regulators requiring a stable reference voltage. The SOT-23-5 package allows for high-density surface mount assembly and is suitable for space-constrained designs. Its lead-free construction adheres to RoHS compliance standards. Choosing this specific part offers a balance of precision, stability, and compact size, making it a robust solution for demanding voltage reference applications.
