Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The device is not guaranteed to function outside its operating range.
Note 3: The maximum allowable power dissipation at any T
Note 4: Output voltage temperature coefficient is the worst case voltage change divided by the total temperature range.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested
Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
