... Note3: The control pin current is the drive current required for the output transistor. The current will track output current with a ratio of about 1:100. Note4: The dropout voltage for the LND1117 is caused by either minimum control voltage or minimum power voltage. The specifications represent the minimum input/output voltage required to maintain 1% regulation. ...

... It is important to note that the voltage drops due to Rp are not eliminated, they will add to the dropout voltage of the regulator regardless. The LND1117 can control the voltage at the load as long as the input-output voltage is greater than the total of the dropout voltage of the device plus the voltage drop across R ...
