Abstract

This disclosure is directed to a hybrid low dropout voltage regulator circuit, hereinafter referred to as the LDO, including a flipped voltage follower (FVF), coarse grain voltage adjustment circuitry, and fine grain voltage adjustment circuitry. The LDO may provide an output voltage based on receiving a reference voltage. The flipped voltage follower may supply the output voltage to one or more other electronic circuits. The coarse grain voltage adjustment circuitry and the fine grain voltage adjustment circuitry may adjust the output voltage based on a desired voltage level. The LDO may use feedback signals, feedforward signals, or both to provide the output voltage.
