Abstract
A voltage regulator includes a pre-regulation circuit and a low drop-out voltage regulator. The pre-regulation circuit is configured to generate a first power supply voltage based on an input voltage. The low drop-out voltage regulator is configured to generate a second power supply voltage based on the first power supply voltage. Additionally, the low drop-out voltage regulator is configured to filter a low-frequency component of the first power supply voltage.
