Abstract :
A 1.8 V capacitor-free linear regulator with fast transient response based on a new topology with a fast and slow regulation loop is presented. The design has been laid out and simulated in a 0.18 μm CMOS process. The design has a low component count and is tailored for system-on-chip integration. A current step load from 0-50 mA with a rise time of 1 μs results in an undershoot in the output voltage of 140 mV for a period of 39 ns. The regulator sources up to 50 mA current load.
