摘要
A low-power low-dropout (LDO) voltage regulator device includes an error amplifier, a level-shifter circuit, and an NMOS pass transistor. The error amplifier compares a sampled portion of a regulated output voltage of the LDO voltage regulator with a reference voltage and generates an error signal. The level-shifter circuit is coupled to the error amplifier. The NMOS pass transistor provides the regulated output voltage with low dropout operation. The level-shifter circuit can shift a voltage level of the error signal to facilitate the low dropout operation of the NMOS pass transistor.
