Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.

1. 10 second maximum.

2. 60 second maximum above 183

°C.

3. Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output

voltage due to thermal gradients or temperature changes must be taken into account separately.

4. Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4” from the bottom of the package.

5. Dropout voltage is a measurement of the minimum input/output differential at full load.

6. The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used to set the

output voltage is selected to meet the minimum requirement.

7. Guaranteed by design, not 100% tested in production.

8. Thermal shutdown is 100% functionally tested in production.
