Precautions for Use
1. The connecting wiring of C
O
and each terminal must be as short as possible. Owing to type, value and wiring condition of
capacitor, it may oscillate. Confirm the output waveform under the actual condition before using.
2. ON/OFF control terminal is compatible with LS-TTL. It enables to be directly drive by TTL or C-MOS standard logic
(RCA4000 series) . If ON/OFF control terminal is not used, it is recommended to directly connect applicable terminals with input
terminal.
3. If voltage is applied under the conditions that the device pin is connected divergently or reversely, the deterioration of
characteristics or damage may occur. Never allow improper mounting.
4. If voltage exceeding the voltage of DC input terminal is applied to the output terminal , the element may be damaged.
Especially when the DC input terminal is short-circuited to the GND in ordinary operating state, charges accumulated in the
output capacitor C
O
flow to the input side, causing damage to the element. In this case, connect the ordinary silicon diode as shown
in the figure.

1. Output voltage is able to set (1.5V to 5V) when resistors R
1
, R
2
are attached to , , terminals. As for the external resistors to
set output voltage, refer to the following figure and Fig.18.
