5. The functional range of V
IN
is the voltage range over which the device will function. Output current and internal parameters may deviate from
normal values for V
IN
and V
CC
voltages between 6.3 V and 8 V, depending on load conditions
6. V
CC
should not be driven from a voltage higher than V
IN
or in the absence of a voltage at V
IN
.
7. Guaranteed by design.
