PRECAUTIONS FOR USE

When such a high voltage as exceeds 10V beyond the fixed output voltage (Typ. value) of IC is applied to the output terminal of IC,

the IC may be destroyed. In such a case, it is advised to prevent an excessive voltage from being applied to the IC by connecting

a zener diode between the output terminal and the GND. Especially, in the current boost circuit as shown in example (2) of application

circuits, an input voltage may be suddenly applied to the output terminal of IC in the form of steps, and that in case of light load,

an excessive voltage may be transiently applied to the output terminal of IC: So that great care should be taken to this matter.

In this case, in addition to the above, it may become necessary to consider such a countermeasure as the output capacitor in use is replaced

with a capacitor of larger capacitance, or as R1 (a resistor for IC bias current) or bypass is replaced with a resistor of smaller resistance

according to circumstance or as the input voltage is gradually raised.
