NCP161ASN180T1G Description

Short technical summary and product information.

The NCP161ASN180T1G from On Semiconductor is a linear voltage regulator designed for RF and analog circuits. It offers a fixed output voltage of 1.8V and can supply up to 450mA of current.

 

Key features include ultra-low noise, high Power Supply Rejection Ratio (PSRR), and very low dropout voltage. The device is stable with small ceramic capacitors, making it suitable for space-constrained designs.

 

This regulator operates within an input voltage range of 1.9V to 5.5V and features protection mechanisms such as over current, over temperature, and soft start. It is available in a compact SOT-23-5 surface-mount package.

 

Typical applications include battery-powered equipment, wireless LAN devices, smartphones, tablets, cameras, DVRs, STBs, and camcorders.
