Abstract:
A low dropout regulator includes a first stage that generate a first output voltage and a second stage that generates a second output voltage different from the first output voltage. The first stage and the second stage are coupled in parallel to a node, the stages are selectively controlled respective first and second output signals based on different conditions. One condition may be operation of a load in one or more predetermined modes. Another condition may be transition between modes. Selective control of the first stage during a mode transition may reduce voltage undershoot or voltage overshoot in the load.
