SUPER-SMALL PACKAGE CMOS VOLTAGE REGULATOR
S-817 Series
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 µA.
Compared with the conventional voltage regulator, it is
of low current consumption, and with a lineup of the
super small package (SNT-4A:1.2 x 1.6mm). It is
optimal as a power supply of small portable device.
