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.
