Unless otherwise specified, the following specifications apply over the operating ambient temperature 0°C
pulse testing techniques are used which maintains junction and case temperatures are equal to the ambient temperature.
Note 1: Dropout is caused by either minimum control voltage (V
Note 2: The control pin current is the drive current required for the output transistor. This current will track output current with roughly a 1:100 ratio.
Note 3: Minimum load current is defined as the amount of output current required to maintain regulation. Typically this current provides the bias to the
