A low-dropout (LDO) voltage regulator for generating an output voltage is
disclosed. The voltage regulator includes a startup circuit, a curvature
corrected bandgap circuit, an error amplifier, a metal oxide
semiconductor (MOS) pass device and a voltage slew rate efficient
transient response boost circuit. The MOS pass device has a gate node
which is coupled to the output of the error amplifier, and a drain node
for generating the output voltage. The voltage slew rate efficient
transient response boost circuit applies a voltage to the gate node of
the MOS pass device to accelerate the response time of the error
amplifier in enabling the LDO voltage regulator to reach its final
regulated output voltage when an output voltage drop occurs in the LDO
voltage regulator.
