Circuit operation
(1) The basic application examples are shown in Fig.3. The externally installed parts are only the input and output
smoothing capacitors.
(2) Switching on and off the output voltage is allowed. The output can be switched off by making pin 7 to be low or open
(high impedance). (See Fig.4.)
(3) Fine adjustment of the output voltage is allowed. The fine adjustment of output voltage can be performed from pin 1
via the resistor by connecting the output terminal (pin 2, 3) and GND. (See Fig.5.)
