Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress rat-
ings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of
the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability

Note 1: (V
IN
-V
OUT
) is limited to keep the product (I
OUT
x (V
IN
- V
OUT
)) from exceeding the package power dissipation
limits.
Note 2: Dropout Voltage is (V
IN
- V
OUT
) when V
OUT
falls to 100mV below its nominal value at V
IN
= V
OUT
+1V. For
example, the G9612 is tested by measuring the V
OUT
at V
IN
= V
OUT
+1V, then V
IN
is lowered until V
OUT
falls
100mV below the measured value. The difference (V
IN
- V
OUT
) is then measured and defined as
V
DO
.
Note 3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
