NCV4276ADT50RKG: A 5.0V, 400mA Low-Dropout Voltage Regulator from onsemi

In the realm of power management, efficiency and reliability are paramount. The NCV4276ADT50RKG from onsemi stands out as a robust solution, engineered to deliver a stable 5.0V output voltage at currents up to 400mA. This low-dropout (LDO) voltage regulator is designed to excel in demanding automotive and industrial environments, where consistent performance under variable conditions is non-negotiable.

A key feature of this regulator is its remarkably low dropout voltage. With a typical dropout of just 450mV at 400mA, it can maintain regulation even when the input voltage dips very close to the output level. This capability is crucial for battery-powered applications, where maximizing usable energy and extending operational life are critical. Furthermore, the device incorporates advanced protection mechanisms, including current limiting, thermal shutdown, and reverse battery protection (-40V), ensuring system integrity against fault conditions and enhancing long-term durability.

The NCV4276ADT50RKG is also characterized by its low quiescent current and high accuracy. Its initial output voltage accuracy is within ±2%, providing a precise power rail for sensitive loads. The device is offered in a space-efficient DPAK-5 surface-mount package, making it suitable for PCB designs where area is constrained. Its automotive-grade qualification (AEC-Q100) guarantees performance across a wide temperature range from -40°C to +125°C, making it an ideal choice for under-the-hood automotive electronics, body control modules, and industrial control systems.

ICGOOODFIND: The NCV4276ADT50RKG is a highly reliable, feature-rich LDO regulator that combines low dropout voltage, robust protection features, and automotive-grade robustness, making it an excellent choice for stabilizing power rails in harsh electrical environments.
