I have corrected it now & will push in next revision.
regulators is expected to have subnode vout0. like below:
  regulators:
    type: object
    description:
      list of regulators provided by this controller.

    properties:
      vout0:
        $ref: /schemas/regulator/regulator.yaml#
        type: object

        unevaluatedProperties: false

    additionalProperties: false
