ULTRA COMPACT CMOS VOLTAGE REGULATOR
S-817 Series
The S-817 is an ultra compact 3-pin positive voltage
regulator developed using CMOS technology. Housing into
a miniaturized 2.0 x 2.1 mm SC-82AB package, the S-817
offers key advantages for small, portable applications.
The S-817 allows many types of output capacitors including
ceramic capacitors and ensures highly-stable operations at
light load as low as 1µA.
