R1540x. APPLICATION INFORMATION. Typical Application for IC Chip Breakdown Prevention
Model Line for this Datasheet
Text Version of Document
R1540x
NO.EA-513-190411
APPLICATION INFORMATION Typical 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. VDD VOUT VOUT CIN
