Vcont pin
No.A0927-4/5
ID =
VZ
r
(= constant)
As shown in the above diagram, the Vcont pin outputs the voltage of the band gap Zener VZ + VF (=1.93V).
In normal use, this pin is left open.
The drive current ID is varied by the Vcont voltage. However, because the band gap Zener is shared, it functions as a
bridge.
