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 increases
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
and to reduce the junction temperature as a result.
in the input terminal,
SD
The power dissipation P of IC is expressed in the following equation.
D
If V ' is reduced below the lowest voltage necessary for the IC, the parasitic oscillation will be caused
IN
according to circumstances.
In determing the resistance value of R , design with margin should be made by making reference to
SD
the following equation.
(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 PCB patterns. In
particular, adequate investigation should be made so that there is no problem even at time of high or
low temperature.

(5) The molded plastic portion of this unit, measuring 5.5 mm
(L) by 6.8 mm (W) by 2.5 mm (T), is more comapact
compared to its equivalents TO-220.
The GND fin extends directly out of the main body, and can
be soldered directly to the ceramic circuit board, to
significantly increase the power dissipation.
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).
j
Further, full consideration should be given to the
installation of IC to the heat sink.
