ONSEMI NCP163ASN180T1G Ultra-Low Noise LDO Regulator

The NCP163 is a high PSRR, ultra-low noise LDO regulator capable of delivering 250 mA, ideal for RF and sensitive analog circuits. It features excellent load/line transient response, operating from 2.2 V to 5.5 V input with a fixed output voltage option from 1.2 V to 5.3 V. The device provides ultra-low noise, low quiescent current (typ. 12 nA), high power supply rejection, and stability with small ceramic capacitors. Available in compact WLCSP, XDFN, and SOT23 packages, it is suitable for battery-powered wireless devices and high-performance applications.
