The S-1200 Series, developed by using CMOS technology, is a positive voltage regulator with a low dropout
voltage, high accuracy output voltage.
A 0.1 μF small ceramic capacitor can be used. It operates with low current consumption of 18 μA typ.
The built-in output current protection circuit prevents the load current from exceeding the current capacity of the
output transistor.
Compared with the voltage regulators using the conventional CMOS technology, small ceramic capacitors are
also available. Furthermore, the small HSNT-6A package realizes high-density mounting.
