A voltage regulator including a comparing circuit, a first circuit, a transistor, a voltage reference circuit, and a latching circuit. The comparing circuit compares a first and second voltage references and generates an output based on the comparison. The first circuit amplifies the output of the comparing circuit. The transistor includes: a gate configured to receive a first output of the first circuit; a first terminal connected to a voltage supply terminal; and a second terminal. A regulated output voltage of the voltage regulator is based on a voltage at the second terminal. The voltage reference circuit generates the second voltage reference based on the voltage at the second terminal. The latching circuit, based on a second output of the first circuit: adjusts the second voltage reference; and switches between forcing the second output of the first circuit to be in a first state to be in a second state.
