Note 2:For the adjustable device the minimum load current is the minimum current roquired to maintain regulation. Normally

the current in the resistor divier used to set the output voltage is selected to meet the minimum load current requiement.

Note 3: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.

Note 4:The dropout voltage for the CS5201 is caused by either minimum control voltage or minimum power voltage.

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