Precautions for Use
Destruction of the IC may occur if high voltage in excess of the IC output voltage (typ. value) is applied to the IC
output terminal. Where this possibility exists, connect a Zener diode between the output terminal and GND to
prevent any application of excessive voltage. In particular, in a current boosting circuit such as that shown in
Application Circuit Example (2), if the input voltage is suddenly applied by stages and, furthermore, load is light,
excessive voltage may be applied transiently to the output terminal of the IC. In such a case, it may become
necessary to increase the capacity of the output capacitor as appropriate, use a smaller R
IC bias current) or gradually raise the input voltage, in addition to using a Zener diode as mentioned above.
