S-817 Series SUPER-SMALL PACKAGE www.ablic.com CMOS VOLTAGE REGULATOR www.ablicinc.com © ABLIC Inc., 1999-2015 Rev.6.2_02 The S-817 Series is a 3-terminal positive voltage regulator, developed using CMOS technology. Small ceramic capacitors can be used as the output capacitor, and the S-817 Series provides stable operation with low loads down to 1 A. Compared with the conventional voltage regulator, it is low current consumption, and with a lineup of the super small package (SNT-4A:1.2 mm  1.6 mm). It is optimal as a power supply of small portable device.  Features  Output voltage: 1.1 V to 6.0 V, selectable in 0.1 V step  Output voltage accuracy: 2.0%  Dropout voltage: 160 mV typ. (5.0 V output product, IOUT  10 mA)  Current consump
