LOW DROPOUT CMOS VOLTAGE REGULATOR
© SII Semiconductor Corporation, 2004-2015
Rev.3.1_01
The S-1711 Series is a 2-channel positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and
low current consumption (150 mA output current) developed based on CMOS technology.
A 1.0 μF small ceramic capacitor can be used, and a 2-circuit voltage regulator with ±1.0% high-accuracy output voltage is
incorporated in SOT-23-6 or super-small SNT-6A package. A/ B/ E/ F type is provided with a discharge shunt function
allowing high-speed output response when the ON/OFF pin is used.
Compared with the conventional 150 mA output current 2-channel CMOS voltage regulators, high-density mounting is
realized by using super-small SNT-6A package and a small ceramic capacitor. Also, the low current consumption makes
the S-1711 Series ideal for mobile devices.
Features
Output voltage:
1.5 V to 5.5 V, selectable in 0.1 V step
Input voltage:
2.0 V to 6.5 V
Output voltage accuracy:
±1.0%
Dropout voltage:
200 mV typ. (3.0 V output product, IOUT = 150 mA)
Current consumption:
During operation: 70 μA typ., 90 μA max. (Per circuit)
During power-off: 0.1 μA typ., 1.0 μA max.
Output current:
Possible to output 150 mA (VIN VOUT(S) + 1.0 V)*1 (Per circuit)
Input and output capacitors:
A ceramic capacitor of 1.0 μF or more can be used.
Ripple rejection:
70 dB typ. (f = 1.0 kHz)
Built-in overcurrent protection circuit: Limits overcurrent of output transistor.
Built-in ON/OFF circuit:
Ensures long battery life.
Pull-up or pull-down resistor is selectable.
Discharge shunt function is selectable.
Operation temperature range:
Ta = 40°C to +85°C
Lead-free, Sn 100%, halogen-free*2
