ELECTRICAL CHARACTERISTICS
(V
Note 1. Exceeding the absolute maximum rating may damage the device.
Note 2. The device is not guaranteed to function outside its operating rating.
Note 3: The maximum allowable power dissipation at any T (ambient temperature) is P (max) = (T (max) -T )
Note 4: Output voltage temperature coefficient is defined as 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 for load regulation in the
Note 6: Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at
Note 7: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the
Note 8: Thermal regulation is defined as the change in output voltage at a time "t" after a change in power dissipation is applied, excluding load
