Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings

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: (VIN-VOUT) is limited to keep the product (IOUT x (VIN - VOUT)) from exceeding the package power dissipation limits.

Note 2: Dropout Voltage is (VIN - VOUT) when VOUT falls to 100mV below its nominal value at VIN = VOUT+1V. For example, the

G9612 is tested by measuring the VOUT at VIN = VOUT+1V, then VIN is lowered until VOUT falls 100mV below the meas-

ured value. The difference (VIN - VOUT) is then measured and defined as ΔVDO.

Note 3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
