HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR
S-812C Series
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
power-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.
