A fast loop amplifier provides low-dropout (LDO) regulation for a frequency range. In one embodiment, the fast loop amplifier may include a two-stage amplifier that decouples gain from bandwidth. In another embodiment, the LDO regulator may include an alternating current coupling capacitor having increased capacitance (e.g., twice that of a load capacitance) and adding one or more gate blocking capacitors. The load capacitance may include a sum of a capacitance of the one or more gate blocking capacitors and parasitic capacitances of the fast loop amplifier. The AC coupling capacitor and the one or more gate blocking capacitors may improve base open-loop power supply rejection ratio and load regulation. In yet another embodiment, bias generation circuitry of the fast loop amplifier may include an amplifier coupled to the fast loop amplifier that reduces gain variations across process, voltage, and/or temperature, and maintains current density with respect to gain programing.
