HIGH RIPPLE-REJECTION AND LOW DROPOUT HIGH OUTPUT CURRENT
CMOS VOLTAGE REGULATOR
S-1170 Series
The S-1170 Series is a positive voltage regulator with
a low dropout voltage, high output voltage accuracy,
and low current consumption developed based on
CMOS technology.
A built-in low on-resistance transistor provides a low
dropout voltage and large output current, a built-in
overcurrent protector prevents the load current from
exceeding the current capacitance of the output
transistor, and a built-in thermal shutdown circuit
prevents damage caused by the heat. An ON/OFF
circuit ensures a long battery life. Compared with the
voltage regulators using the conventional CMOS
process, a larger variety of capacitors are available,
including small ceramic capacitors. Small SOT-89-5
and 6-Pin HSON(A) packages realize high-density
mounting.
