Abstract:
Low dropout regulators (LDOs) are disclosed herein. An example of an LDO includes an error amplifier having a first input and a second input, wherein the first input is for coupling to an output of the LDO and the second input for coupling to a reference voltage. The error amplifier has an output with a voltage that is proportional to the difference between the output voltage and the reference voltage. A second amplifier is coupled between the error amplifier and the output of the LDO. A gain boost amplifier is coupled between the error amplifier and the second amplifier. The gain boost amplifier increases DC gain of the LDO in response to a load step on the output.
