The NR\/SS pin allows an external capacitor to filter reference noise and control soft-start. The external bias (BIAS) pin enables the internal LDO that drives the gate of the pass transistor, reducing dropout voltage below 200mV. The power-good (PG) output provides output voltage monitoring. The 4.17uVrms noise is achieved through careful circuit design, layout, and the NR capacitor filtering mechanism.","pin_description":"
