HIGH RIPPLE-REJECTION LOW DROPOUT
HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR
S-1170 Series
Seiko Instruments Inc.
1
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.
Features
Output voltage:
1.5 V to 5.5 V, selectable in 0.1 V steps.
High-accuracy output voltage:
1.0%
Low dropout voltage:
120 mV typ. (3.0 V output product, I
OUT
= 300 mA)
Low current consumption:
During operation: 80
A typ., 160 A max.
During shutdown: 0.1
A typ., 1.0 A max.
High peak current capability:
800 mA output is possible (@ V

Built-in ON/OFF circuit:
Ensures long battery life.
Low ESR capacitor can be used: A ceramic capacitor of 4.7 F or more can be used for the output
capacitor.
High ripple rejection:
70 dB typ. (@ 1.0 kHz)
Built-in overcurrent protector:
Overcurrent of output transistor can be restricted.
Built-in thermal shutdown circuit: Damage caused by heat can be prevented.
Small package:
SOT-89-5, 6-Pin HSON(A)
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
Power supply for DVD and CD-ROM drives
Power supply for battery-powered devices
Power supply for personal communication devices
