NCP161AFCS300T2G Description

Short technical summary and product information.

The NCP161AFCS300T2G from ON Semiconductor is a 450mA linear regulator designed for RF and analog circuits requiring low noise and high Power Supply Rejection Ratio (PSRR). It operates with an input voltage range of 1.9V to 5.5V and provides a fixed 3V output.

 

Key features include ultra-low quiescent current (18 µA typical), very low dropout voltage (150 mV at 450 mA), and high PSRR (98 dB at 1 kHz). The device is stable with small ceramic capacitors and includes protection features such as over current, over temperature, and soft start.

 

This regulator is available in an ultra-small 4-WLCSP package (0.64mm x 0.64mm), making it suitable for space-constrained applications. It is also available in XDFN4 and SOT23-5 packages. The operating temperature range is -40°C to 125°C.

 

Typical applications include battery-powered equipment, wireless LAN devices, smartphones, tablets, cameras, DVRs, STBs, and camcorders where low noise and high performance are critical.
