Note2: 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.
Note3: 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
Note4: If the same voltage is input to both V
POWER
and V
CONTROL
, then the dropout voltage will become 1.3V maximum,
and minimum input/output voltage required to maintain 1% regulation.
