ABSTRACT:
An error amplifier of a low dropout regulator includes a compensation network configured to adapt the error amplifier to varying load currents. The compensation network may be coupled to an amplifier stage of the error amplifier. For example, the compensation network may be coupled across an input and an output of the amplifier stage in a Miller connection. As another example, one end of compensation network may be coupled to an input of the amplifier stage with another end coupled to ground. The compensation network may have several resistors and capacitors that have corresponding parameter switches for switching the resistors and capacitors in and out of the compensation network to change a parameter of the compensation network based on load current.
