Notes:

1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating

regulator will go into thermal shutdown. See Table 1 and the “Thermal Considerations” section for details.

2. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.

3. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from

100mA to 500mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.

4. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential.

5. 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

current plus the ground pin current.

7. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line

8. The error flag comparator includes 3% hysteresis.
