UNITS 60 80 - dB - - 0.02 %/W Thermal Regulation VPWR = 5V, ILOAD = 7A, PD > 20W, 30ms Pulse Dropout Voltage Dropout voltage is caused by either minimum control voltage or minimum power voltage. Both parameters are specified with respect to the output voltage. The specifications represent the minimum input/output voltage required to maintain 1% 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. It is roughly 1% of the output current. The minimum value is equal to the quiescent current.
