1.1
(Unless otherwise specified, these specifications apply over the operating ambient temperatures 0°C ≤ T
techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
Note 2. Dropout is caused by either minimum control voltage (V
Note 3. 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.
