R1540x-Y NO.EY-513-190411 APPLICATION INFORMATIONTypical Application for IC Chip Breakdown Prevention A sudden surge of current flowing through the VOUT pin during a short to GND leads to negative voltage due to resonance generated between the impedance of the wire and the output capacitor, C2. Consequently, large short-circuit current may destroy the IC or a load device in some types of pattern boards. It is highly recommended to connect schottky diode, D1, between VOUT pin and GND to prevent the IC from being destroyed.
