1. A programmable low dropout regulator comprising:

  • an error amplifier including an output and a first input;

    a regulation field-effect transistor including a gate electrically connected to the output of the error amplifier and a drain electrically connected to an output node configured to provide a programmable output voltage that is programmable to a plurality of different voltage levels;

    a feedback circuit electrically connected between the output node and a first voltage, the feedback circuit configured to provide a feedback signal to the first input of the error amplifier;

    an output capacitor electrically connected to the output node; and

    an alternative discharge circuit configured to activate to discharge the output capacitor in response to programming the programmable output voltage from a high voltage level to a low voltage level.
