Electrical Characteristics
Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, Tj, the junction
Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed
Note 2: Maximum positive supply voltage of 60V must be limited duration (<100mS) and duty cycle (<1%).
Note 3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
Note 4: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the
Note 5: Output current will decrease with increasing temperature, but it will be not dropped below 1A at the maximum
