1. External connection
(1) The connecting wiring of C
O,
C
IN
and each terminal, fin portion must be as short as possible. It may oscillate by type, value and
wiring condition of capacitor. Confirm the output wareform in actual using condition beforehand.
(2) ON/OFF control terminal is compatible with LS-TTL. It enables to be direcrly driven by TTL or C-MOS standard logic
(RCA4000 series).
(3) If voltage is applied under the conditions that device pin is connected divergently or reversely, the deterioration of
characteristics or damage may occur. Never allow improper mounting.
2. Thermal protection design
Power dissipation of devices is obtained by the following equation.
P
D
=
I
O
(V
IN
-
V
O
)
+
V
IN
I
q
When ambient temperature T
a
and power dissipation P
D
during operation are determined, operate element within the safety
operation area specified by the derating curve. Insufficient radiation gives an unfavorable influence to the normal operation and
reliability of the device.
In the external area of the safety operation area shown by the derating curve, the overheat protection circuit may operate to shut-
down output. However please avoid keeping such condition for a long time.
3. ESD (Electrostatic Sensitivity Discharge)
Be careful not to apply electrostatic discharge to the device since this device employs a bipolar IC and may be damaged by electro
static discharge. Followings are some methods against excessive voltage caused by electro static discharge.
(1) Human body must be grounded to discharge the electro charge which is charged in the body or cloth.
(2) Anything that is in contact with the device such as workbench, inserter, or measuring instrument must be grounded.
(3) Use a soldering dip basin with a minimum leak current (isolation resistance 10M
or more) from the AC power supply line.
Also the soldering dip basin must be grounded.

Output Voltage Fine Tuning
1. Connecting external resistors R

and R
2
to terminals , , allows the output voltage to be fine tuned from 1.5V to 7V. Refer to
