NCP703SN19T1G

The NCP703 is one of the best in class regulators for providing both low noise performance (PSRR of 68 dB and noise levels typically < 13 uVrms) and a low quiescent operating current (< 12 uA), thanks to its BiCMOS process technology. In contrast to the tradeoff of noise vs. consumption found in some CMOS products, the NCP703 does not compromise, making it an ideal device for use with image sensors in cell phones and for noise sensitive circuits in other battery products. With output voltages as low as 0.8V, the NCP703 requires only 180 mV across the input and output. It is available in TSOP5 and XDFN 1.5x1.5mm packages.
