2_00 HIGH RIPPLE-REJECTION LOW DROPOUT LOW INPUT-AND-OUTPUT CAPACITANCE CMOS VOLTAGE REGULATOR S-1200 Series The S-1200 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy developed based on CMOS technology.
A 0.
1 µF small ceramic capacitor can be used.
It operates with low current consumption of 18 µA typ.
A built-in Output current protector prevents the load current from exceeding the current capacitance of the output transistor.
Compared with the voltage regulators using the conventional CMOS process, small ceramic capacitors are also available.
Furthermore a small SNT-6A(H) and SOT-23-5 packages realize highdensity mounting.
