Abstract
Provided is a voltage regulator having satisfactory transient response characteristics. Because a PMOS (25) and an NMOS (24) pass drain currents (charge and discharge currents with respect to gate of PMOS (26)) based on the square of voltage (ΔIR) according to change (ΔI) in drain currents of NMOSs (16 and 17), a maximum value (Imax) of the charge and discharge currents becomes larger, transition time (t) of gate voltage of the PMOS (26) becomes shorter, and the transient response characteristics of the voltage regulator become better.
