NCP161AMX185TBG Description

Short technical summary and product information.

The NCP161AMX185TBG from ON Semiconductor is a linear regulator designed for RF and analog circuits, offering 450mA of output current. It features an ultra-low noise profile and high Power Supply Rejection Ratio (PSRR), making it suitable for sensitive applications.

 

This device operates within an input voltage range of 1.9V to 5.5V and provides a fixed output voltage of 1.85V with ±2% accuracy over load and temperature variations. It boasts very low dropout voltage (150mV at 450mA) and ultra-low quiescent current (18µA typical).

 

The NCP161AMX185TBG is available in a compact 4-XDFN (1x1 mm) package, suitable for surface mounting. It includes protection features such as over current, over temperature, and soft start, enhancing reliability. The regulator is stable with small ceramic capacitors, simplifying external component selection.

 

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