摘要

通过在传统的LDO电路中加入米勒频率补偿，将超级源跟随器和电压尖峰检测相结合，提出了一种低功耗LDO电路，可以快速调节负载，驱动负载电容达到10 pF。LDO电路将5v输入转换为3.3V输出，功耗26 μA，在10ma负载电流阶跃下，在1ns内稳定在75ns。

A low-power LDO circuit with a fast load regulation

By adding a Miller frequency compensation to the conventional LDO circuit that combines the super source follower and the voltage spike detection, a low-power LDO circuit is proposed to drive the load capacitance up to 10 pF with a fast load regulation. The LDO circuit converts a 5 V input to a 3.3V output, consumes 26 μA, and settles in 75 ns at a 10 mA load current step in 1ns.
