HIGH RIPPLE-REJECTION AND LOW DROPOUT
HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR

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, IOUT = 300 mA)
Low current consumption:
During operation: 80
μA typ., 160 μA max.
During shutdown: 0.1
μA typ., 1.0 μA max.
High current capability:
800 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)
*1
Built-in ON/OFF circuit:
Ensures long battery life.
Low ESR capacitor can be used: A ceramic capacitor of 4.7 μF or more can be used for the output
capacitor.
High ripple rejection:
70 dB typ. (at 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.
Lead-free, Sn 100%, halogen-free*2
*1. Attention should be paid to the power dissipation of the package when the output current is large.
*2. Refer to “
Product Name Structure” for details.
