The S-1324 Series, developed by using the CMOS technology, is a positive voltage regulator IC which has low noise and low
dropout voltage.
Output noise is as low as 17 μVrms typ., and a ceramic capacitor of 1.0 μF or more can be used as the input and output
capacitors.
It also has high-accuracy output voltage of 1.0%.
