Abstract
A low-dropout regulator architecture with undershoot mitigation. In one embodiment, a system including a low-dropout regulator and a digital-to-analog converter (DAC). The low-dropout regulator is configured to generate a load current and output a voltage at an output node. The digital-to-analog converter (DAC) is configured to receive a control input, and output a DAC current to the low-dropout regulator based on the control input. The DAC current is configured to modify the load current and mitigate an undershoot of the voltage that is output at the output node while the voltage transitions from a high voltage level to a low voltage level.
