Figure 9. Constant Current Regulator

Notes:

(1) To specify an output voltage. substitute voltage value for "XX." A common ground is required between the input and the

Output voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input

ripple voltage.
