Note 3: All operating conditions include the combined effects of load
current, input voltage and temperature over each parameter’s full range.
Note 4: Load and line regulation are tested at a constant junction
temperature by low duty cycle pulse testing.
Note 5: Dropout voltage is defined as the minimum input to output voltage
measured while sourcing the specified current.
