Abstract
A push-pull Low Dropout (LDO) voltage regulator is provided. An instantaneous output voltage of the push-pull LDO voltage regulator is compared with a first reference voltage and a first output based on comparing the first reference voltage with the instantaneous output voltage is provided. The instantaneous output voltage of the push-pull LDO voltage regulator is compared with a second reference voltage and a second output based on comparing the instantaneous output voltage with the second reference voltage is provided. One or more bi-directional drivers of a plurality of bi-directional drivers of the push-pull LDO voltage regulator are driven based on the first output and the second output. The plurality of bi-directional drives provide the predetermined output voltage.
