1. A circuit comprising:
voltage regulators configured in parallel;
an input circuit comprising an input controller, the input circuit being coupled to an input of at least one voltage regulator of the voltage regulators; and
an output circuit comprising an output controller, the output circuit being coupled to an output of the at least one voltage regulator, the output controller being coupled to the input circuit to cause the input circuit to prevent power to the at least one voltage regulator in response to the output controller detecting an overvoltage condition, wherein the output controller is connected to a latch, the latch being connected to a pull-down circuit, the pull-down circuit being connected to the input controller, the latch preventing the output controller from being directly connected to the pull-down circuit.
