1. A power supply regulator, comprising:

  • an electrical terminal coupled to receive an input signal representing an input voltage of the power supply regulator, the electrical terminal further coupled to receive a feedback signal representative of a power supply output to be regulated by the power supply regulator;

    an undervoltage detector coupled to the electrical terminal to receive the input signal to detect an undervoltage condition; and

    a circuit coupled to the electrical terminal to receive the feedback signal to regulate the power supply output, the circuit to disable the power supply if the undervoltage condition is detected by the undervoltage detector.
