Claim:
1. A voltage regulator comprising: a comparing circuit configured to (i) compare a first voltage reference to a second voltage reference, and (ii) generate an output based on the comparison between the first voltage reference and the second voltage reference; a first circuit configured to amplify the output of the comparing circuit; a first transistor comprising (i) a gate configured to receive a first output of the first circuit, (ii) a first terminal connected to a voltage supply terminal, and (iii) a second terminal, wherein a regulated output voltage of the voltage regulator is based on a voltage at the second terminal of the first transistor; a voltage reference circuit configured to generate the second voltage reference based on the voltage at the second terminal of the first transistor; and a latching circuit configured to, based on a second output of the first circuit, (i) generate an output to adjust the second voltage reference, and (ii) switch between (a) forcing the second output of the first circuit to be in a first state to (b) forcing the second output of the first circuit to be in a second state.
