Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation at any T
3. The maximum allowable power dissipation at any T
3. The maximum allowable power dissipation at any T (ambient temperature) is calculated using: P
4. Output voltage temperature coeffi cient is the worst case voltage change divided by the total temperature range.
5. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range
6. Dropout voltage is defi ned as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differen-
7. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load
