Note 1. Stresses listed as the absolute maximum ratings may cause permanent damage to the device. These are for stress ratings. Functional
operating of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not
implied. Exposure to absolute maximum rating conditions for extended periods may remain possibly to affect device reliability.
Note 2. The minimum operating value for input voltage is equal to either (V
OUT,NOM
+ V
DROP
) or 2.5V, whichever is greater.
Note 3. Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the input line voltage.
Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in load current.
Note 4. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for load regulation in the
load range from 10mA to 1.5A
Note 5. Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value.
Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the dropout voltage is
nothing but the input to output differential, since the minimum input voltage is 2.5V
Note 6. Ground current, or quiescent current, is the difference between input and output currents. It's defined by I
GND1
= I
IN
- I
OUT
under the
given loading condition. The total current drawn from the supply is the sum of the load current plus the ground pin current.
Note 7. Ground current, or standby current, is the input current drawn by a regulator when the output voltage is disabled by an enable signal.
