Dropout is caused by either minimum control voltage or minimum power voltage. Both
Dropout Voltage
parameters are specified with respect to the output voltage. The specifications represent the
minimum input/output voltage required to maintain 1% regulation.
Footnotes
Q- Denotes specifications which apply over the full operating temperature range.
R- The minimum load current is 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.
S- The control pin current is the drive current required for the output transistor. The control pin current is
approximately 0.01% output current. The minimum value is equal to quiescent current of the device.
