DIRECTIONS FOR USAGE
Notes on Usage
1. Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction
2. There is a possibility theat, oscillation may occur as a result of the impedance present between the

power supply and the IC's input. Where impedance is 10W or more, please use a capacitor (C )
of at least 1µF.
With a large output current, operations can be stabilised by increasing capacitor size (C ). If C
small and capacitor size (C ) is increased, there is a possibility of oscillation due to input impedance.
In such cases, operations can be stabilised by either increasing the size of C
of C .
