onsemi Voltage Regulators - Linear NCP163AFCT330T2G

The NCP163AFCT330T2G is a linear voltage regulator designed to provide a fixed output voltage of 3.3 V with a maximum output current of 250 mA. It operates within an input voltage range of 2.2 V to 5.5 V and features an ultra-low quiescent current of approximately 12 µA, making it suitable for battery-powered applications. The device exhibits a low dropout voltage of 80 mV at 250 mA, ensuring efficient performance. This regulator is characterized by high power supply rejection ratio (PSRR) of 92 dB at 20 mA, which is beneficial for maintaining stable output in noisy environments. It also has a low output noise of 6.5 µVRMS, making it ideal for sensitive RF and analog circuits. The NCP163AFCT330T2G is stable with small case size ceramic capacitors of 1 µF for both input and output, and it is available in a compact WLCSP package measuring 0.64 mm x 0.64 mm x 0.33 mm. Additional features include ±2% output voltage accuracy over load and temperature, thermal shutdown protection, and an enable pin for chip activation. The device is RoHS compliant and free from halogens and lead, aligning with modern environmental standards. Typical applications include wireless LAN devices, smartphones, and other portable electronics.
