ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are those values beyond whih damage to the device may occur. Functional
operation under these condition isn’t implied.
For voltages and currents applied externally to the device:

DC Output Load Current
DC Output Current: for VOUT > VVS +0.3V or VOUT < -0.3V
the internal DMOS reverse and/or substrate diode become
conductive and the applied current should not exceed the
specified limit.
