S-1711 Series 6.5 V INPUT, 150 mA, www.ablic.com 2-CIRCUIT VOLTAGE REGULATOR ABLIC Inc., 2004-2019 Rev.3.2 00 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 F 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, I = 150 mA) OUT Current consumption: During operation: 70 A typ., 90 A max. (Per circuit) During power-off: 0.1 A typ., 1.0 A max. *1 Output current: Possible to output 150 mA (V V + 1.0 V) (Per circuit) IN OUT(S) Input and output capacitors: A ceramic capacitor of 1.0 F 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.
