PRECAUTIONS ON APPLICATION
(1) In regard to GND, be careful not to apply a negative voltage to the input/output terminal. Further, special care is necessary in case
of a voltage boost application.
(2) When a surge voltage exceeding maximum rating is applied to the input terminal or when a voltage in excess of the input terminal
voltage is applied to the output terminal, the circuit may be destroyed. Specially, in the latter case, great care is necessary Further,
if the input terminal shorts to GND in a state of normal operation, the output terminal voltage becomes higher than the input voltage
(GND potential), and the electric charge of a chemical capacitor connected to the output terminal flows into the input side,
which may cause the destruction of circuit. In these cases, take such steps as a zener diode and a general silicon diode are connected
to the circuit, as shown in the following figure.

(3) When the input voltage is too high, the power dissipation of three terminal regulator increase because of series regulator,
so that the junction temperature rises. In such a case, it is recommended to reduce the power dissipation by inserting the power
limiting resistor R
in the input terminal, and to reduce the junction temperature as a result.

(4) Connect the input terminal and GND, and the output terminal and GND, by capacitor respectively.
The capacitances should be determined experimentally because they depend on printed patterns. In particular,
adequate investigation should be made so that there is no problem even at time of high or low temperature.
(5) Installation of IC for power supply
For obtaining high reliability on the heat sink design of the regulator IC, it is generally required to derate more than 20%
of maximum junction temperature (T MAX.) Further, full consideration should be given to the installation of IC to the heat sink.
j
(a) Heat sink design
The thermal resistance of IC itself is required from the viewpoint of the design of elements, but the thermal resistance from the
IC package to the open air varies with the contact thermal resistance. Table 1 shows how much the value of the contact thermal
resistance (θ +θ) is changed by insulating sheet (mica) and heat sink grease.

The figures given in parentheses denote the values at time of no grease.
The package of regulator IC serves as GND, therefore, usually use the value at time of "no mica"
(b) Silicon grease
When a circuit not exceeding maximum rating is designed, it is to be desired that the grease should be used if possible.
If it is required that the contact thermal resistance is reduced from the view-point of the circuit design,
It is recommended that the following methods be adopted.
A: Use Thercon (Fuji High Polymer Kogyo K.K)
B: Use SC101 (Torei Silicon) or G-640 (GE), if grease is used.
(c) Torque
When installing IC on a heat sink or the like, tighten the IC with the torque of less than the rated value. If it is tightened with
the torque in excess of the rated value, sometimes the internal elements of the IC are adversely affected. Therefore, great care
should be given to the installing operation. Further, if polycarbonate screws are used, the torque causes a change with the passage
of time, which may lessen the effect of radiation.

(a) IEC (International Electronical Commission)-65 is the standard, parts testing method, machinery and tolls (used in connecting main
power directly and indirectly) Which are used at home and general building. The purpose of the above standard is not to breaking out the
risk which is related to an electric shock, a heating, a fire and the damage of surrounding parts in the case of normal or abnormal operating.
(b) In case temperature is limited by temperature overheating prevention device, fuse or the operation of fuse resistor
One must calculate the temperature of PCB substrate in 2 minute.
