LOW CURRENT CONSUMPTION HIGH RIPPLE-REJECTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.2.3_00
The S-1333 Series, developed by using the CMOS technology, is a positive voltage regulator IC which has low current
consumption, high ripple-rejection and low dropout voltage.
Even with low current consumption of 25 μA typ., it has high ripple-rejection of 75 dB 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%.
