Terminal ※ where the destination of hanging the diode on the power supply side is
REG5 must defend the above-mentioned sequence so as not to impress the voltage
more than the voltage of REG5 terminal.
Please insert in the cereal and use the limit resistance for the terminal when you
impress the voltage more than the voltage of REG5 terminal.
(Limit resistance 10kΩ or more is inserted in the cereal about REGCTL terminal. )
