The S-817 is an ultra compact 3-pin positive voltage
regulator developed using CMOS technology. Due to
housing into an even more miniaturized SC-82AB package
of 2.0 x 2.1 mm, the S-817 offers key advantages for small,
portable applications.
The S-817 allows many type of output capacitors including a
ceramic type and ensures highly-stable operations at low
load of 1
