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 high-
density mounting.
Features
1.5 V to 5.5 V, selectable in 0.1 V steps.
