onsemi Voltage Regulators - Linear NCP161AFCT514T2G

The NCP161AFCT514T2G is a linear voltage regulator designed to provide a fixed output voltage of 5.14 V with a maximum output current of 450 mA. It operates within an input voltage range of 1.9 V to 5.5 V and features an ultra-low quiescent current of approximately 18 µA, making it suitable for battery-powered applications. The device exhibits a low dropout voltage of 150 mV at full load and offers high power supply rejection ratio (PSRR) of 98 dB at 20 mA, ensuring stable performance in sensitive RF and analog circuits. This regulator is available in a compact WLCSP package measuring 0.64 mm x 0.64 mm, which is advantageous for space-constrained designs. It is stable with small case size ceramic capacitors of 1 µF for both input and output, facilitating easy integration into various applications. The NCP161AFCT514T2G is RoHS compliant and free from lead, aligning with modern environmental standards. Typical applications include wireless LAN devices, smartphones, tablets, and other portable electronics.
