Unless otherwise specified Vout = Vsense. For CS52015 (adj) Vadj = OV

For the adjustable device the minimum load current is the minimum current required to maintain regulation.Normally

the current in the resistor divider used to set the output voltage is selected to meet the minimum load current

requirement.

The control pin current is the drive current required for the output transistor. This current will track output current

with a ratio of about 1:100

The dropout voltage for the CS52015 is caused by either minimum control voltage or minimum power voltage.

The specifications represent the minimum input /output voltage required to maintain 1% regulation.
