A
=25°C, unless otherwise specified (Note 3).
Note 2: To prevent the Short Circuit Current protection feature from being prematurely activated, the input
voltage must be applied before a current source load is applied.
Note 3: Production testing at T
A
=25 °C . Over temperature specifications guaranteed by design only.
