HIGH RIPPLE-REJECTION LOW DROPOUT LOW INPUT-AND-OUTPUT
CAPACITANCE CMOS VOLTAGE REGULATOR
Rev.5.0
_00
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 HSNT-6A packages realize high-density mounting.
Features
1.5 V to 5.5 V, selectable in 0.1 V steps.
