ON Semiconductor NCP163ASN180T1G: Ultra-Low Noise, High PSRR, Low Dropout Linear Regulator

The ON Semiconductor NCP163ASN180T1G is a state-of-the-art linear voltage regulator designed to deliver a stable and precise voltage supply. This component is part of ON Semiconductor's extensive portfolio of power management solutions, catering to a wide range of applications that require high performance in a compact package. The NCP163ASN180T1G is particularly well-suited for noise-sensitive applications due to its ultra-low noise output and high power supply rejection ratio (PSRR).

With an output voltage of 1.8V, the NCP163ASN180T1G is capable of sourcing up to 300 mA of output current, making it an excellent choice for portable devices, RF applications, and other systems where power efficiency and minimal noise are critical. The regulator's low dropout voltage ensures efficient operation even when the input-to-output differential is small, conserving battery life in portable applications.

The NCP163ASN180T1G boasts an impressive PSRR of 80 dB at 1 kHz, which significantly reduces the sensitivity to variations in the input voltage, thus providing a more stable output. This feature is particularly important in environments with fluctuating power supplies or in applications where a clean voltage rail is essential for performance, such as precision analog circuits or audio devices.

Another key feature of the NCP163ASN180T1G is its ultra-low noise performance, with an output voltage noise as low as 9 µVrms from 10 Hz to 100 kHz. This makes it an ideal choice for sensitive applications like RF circuits, where noise can significantly impact signal integrity and overall system performance.

The device is housed in a space-saving 2x2 mm DFN-6 package, which allows for high-density circuit designs. Additionally, the NCP163ASN180T1G includes thermal shutdown and current limit features to protect against over-temperature and over-current conditions, ensuring reliable operation under a variety of circumstances.

Overall, the ON Semiconductor NCP163ASN180T1G is a high-quality, reliable voltage regulator that offers exceptional performance for applications demanding low noise and high PSRR. Its small footprint and robust protection features make it an excellent choice for designers looking to optimize their power management solutions.
