ON Semiconductor NCP163AMX280TBG - Low Dropout Voltage Regulator

The NCP163AMX280TBG is a high-performance, low dropout voltage regulator from ON Semiconductor designed to deliver a stable and reliable power supply in a wide range of applications. With an impressive dropout voltage of just 160 mV at 300 mA load, this regulator ensures efficient operation even when the supply voltage is close to the output voltage, making it ideal for battery-operated devices where energy conservation is critical.

This regulator is capable of providing a fixed output voltage of 2.8V, which is a common requirement for many digital and analog circuits. The NCP163AMX280TBG is designed to support an input voltage range from 1.7V to 5.5V, allowing for flexible usage in various circuit configurations. Additionally, its output current capability of up to 300 mA makes it suitable for moderate power needs.

ON Semiconductor has equipped the NCP163AMX280TBG with several protective features to ensure the longevity and reliability of both the regulator and the devices it powers. These include thermal shutdown protection, which prevents damage from overheating, and current limit protection, which guards against excessive current draw that could lead to circuit failure.

The regulator's ultra-low quiescent current of just 1.6 µA (typical) is particularly beneficial for portable and battery-powered applications, as it minimizes the drain on the power source when the device is in standby mode. This feature greatly extends the battery life of portable devices, making the NCP163AMX280TBG an excellent choice for mobile phones, personal media players, and other handheld electronics.

The NCP163AMX280TBG comes in a compact, space-saving 4-bump wafer level chip scale package (WLCSP), which is perfect for applications where board space is at a premium. Its small footprint and low profile make it an ideal solution for space-constrained designs without compromising on performance.

In summary, the NCP163AMX280TBG from ON Semiconductor is a versatile and efficient voltage regulator that offers low dropout, low quiescent current, and robust protection features. Its performance and compact size make it an excellent choice for a wide range of applications, particularly those requiring long battery life and minimal space.
