NJW4184 - 8 - ver.2012-06-27 *the notes of the evaluation when the v o pin is shorted to gnd when evaluated short circuit test, th e ic may break down because of regenerated energy by the parasitic inductance included in wiring pattern. it phenomenon appears conspicuously when output voltage is high(vo=8.0v or more)or connected to inductive load. in case of short circuit in actual applic ation, not likely to destruction of ic because of some of resistance exist between load. if happened above phenomenon by the short circuit test wi th the actual application, recommend connecting schottky barrier diode (sbd) between the v o pin and gnd or using output capacitors that have esr more than 2 ? like a tantalum or aluminum electrolyt ic capacitor.(see below figure) (a)in case of insert schottky barrier diode between the v o pin to gnd NJW4184 v in v out gnd v out v in sbd (b) in case of using the electrolysis condenser or insert series resistance NJW4184 v in v out gnd v out v in connecting resistance(2 ? or more)in series.
