(2) CURRENT BOOST REGULATOR
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
SD
in the input terminal, and to reduce the junction temperature as a result.
