SOT-23-5 (MP005-A)
HSNT-4(0808) (PK004-A)
HSNT-4(1010) (PL004-A)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%.
