The NCP703SN19T1G is a linear voltage regulator from Lingto Electronic Limited, designed to provide a stable output voltage of 1.9 V with a maximum output current of 300 mA. It operates within an input voltage range of 2.0 V to 5.5 V and features an ultra-low quiescent current of 12 µA, making it suitable for battery-powered applications. The device exhibits low noise performance, with an output noise voltage of 13 µVRMS from 100 Hz to 100 kHz, and a high Power Supply Rejection Ratio (PSRR) of 68 dB at 1 kHz, which is beneficial for noise-sensitive RF applications. The NCP703SN19T1G has a typical dropout voltage of 180 mV at 300 mA, ensuring efficient operation. It includes features such as thermal shutdown, current limit protection, and an internal soft-start function to limit inrush current during startup. The regulator is stable with a 1 µF ceramic output capacitor and is available in a compact TSOP-5 package. This product is suitable for various applications, including mobile phones, GPS devices, and other portable electronics requiring reliable voltage regulation.
