  • Floating-gate programmable low-dropout regulator and method therefor
    Patent number: 8400126
    Abstract: In an embodiment, a low-dropout (LDO) regulator includes at least one of a programmable voltage reference and a programmable frequency compensation circuit and is configurable to produce an output voltage. The programmable voltage reference includes a floating-gate transistor coupled to a reference output and configurable for providing a reference voltage to an input of an error amplifier. The programmable frequency compensation circuit is responsive to a programmable current reference circuit that includes at least one floating-gate transistor that is configurable to adjust a frequency compensation parameter. A control circuit is provided to selectively program floating gates of the floating gate transistors to adjust the output voltage and/or to adjust a frequency component of the output voltage.
