  • LDO voltage regulator having efficient current frequency compensation
    Patent number: 6690147
    Abstract: A low drop out linear voltage regulator (200) overcomes the dynamic quiescent current limitation by creating an internal zero that moves in the same direction and has the same amplitude as that of the output pole without sensing a portion of the load current. The low drop out linear voltage regulator (200) having frequency compensation in accordance with the present invention includes an error amplifier (202), a NMOS pass transistor (204), a variable compensation network (Ci, 206), and a stabilization circuit (208, 210, I3, I4). The error amplifier (202) includes a power supply input connected to a first power supply, a non-inverting input coupled to a reference voltage, a inverting input and an output terminal. The NMOS pass transistor (204) includes a source connected to an output terminal of the voltage regulator, a drain coupled to the second power supply, and a gate coupled to the output terminal of the error amplifier. The variable compensation network (Ci, 206) connects to the error amplifier.
