Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed

specifications and test conditions see the electrical characteristics.

Note 2: Maximum positive supply voltage of 35V must be limited duration (<100mS) and duty cycle (<1%).

allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal

Note 3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its

nominal value measured at 1V differential.

Note 4: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of

the ground pin current and output load current.

Note 5: Output current will decrease with increasing temperature, but it will be not dropped below 400mA at the

maximum specified temperature.
