Regulator LEDs are powered by a single regulator such that they can
|
||
|
|
be turned on or off by enabling or disabling the regulator. The available
|
||
|
|
brightness settings will be inferred from the available voltages on the
|
||
|
|
regulator, and any constraints on the voltage or current will need to be
|
||
|
|
specified on the regulator.
