Abstract: The present invention provides an error amplifier and a power supply. In the error amplifier, a pre-amplifier takes an amplification action in response to a fluctuation in a feedback voltage, allowing more accurate selective activation of a pull-up circuit, a pull-down circuit or a steady-state circuit. This can reduce accuracy requirements for OTAs therein and hence design requirements for the error amplifier. Moreover, in the event of a loading transition, the pull-up or pull-down circuit can be selectively activated to sooner pull up or down a voltage at an output terminal of the error amplifier. This effectively improves load transient response performance of the loop while not affecting its loop stability.
