TLC5916 logic power consumption

To properly size a 5V regulator, I'm trying to figure out how much current the logic-only section of the TLC5916 LED driver takes. Data sheet is here:

There's the maximum current, 960 mA, but that's the draw with the chip + the LEDs it's powering, right? In my circuit the LEDs will be run off their own 12 V power circuit, so I only need to know how much the 5V logic part of the chip will use.

Is it the 120 mA I-OUT value?

6-24ma depending on the value of Rext. See page 10, the bottom of the chart, the value IDD.

Thank you sir!
