To prolong the battery life, power efficiency of low dropout regulators can be improved by reducing the power consumption.
This paper used push-pull output amplifier as a linear regulator. Push-pull output amplifier from the GmH and GmL is composed, because the output current is large, Time required to charge or discharge the large pass transistor gate capacitance is greatly reduced, to achieve high slew rate. And joined the slew rate enhancement circuit to increase the slew rate.
The LDO used push-pull output amplifier which increase the slew rate and reduce the quiescent current by TSMC 0.35μm 2P4M CMOS process technology. The input voltage 3.3V and maximum output current of 100mA of the slew rate of less than 2us while load capacitance 470PF.
