Performance Characteristics, VIN =5.0V
(See Note A)
Safe Operating Area, VIN =5.0V
(See Note B)
Note A:
Characteristic data has been developed from actual products tested at 25°C. This data is considered typical for the regulator.
Note B:
Safe Operating Area curves represent conditions at which internal components are at or below manufacturer’s maximum operating temperatures.
