The S-812C Series is a high-withstand voltage regulator IC which is developed by using the CMOS technology.
This IC is suitable for applications which require withstand because its maximum voltage for operation is as high
as 16 V, also for portable device having the low current consumption because this IC not only has the low
current consumption but also a ON/OFF circuit. This IC operates stably due to the internal phase compensation
circuit so that users are able to use ceramic capacitor as the output capacitor.
