论文摘要
本文介绍了稳定的低辍学（LDO）电压调节器拓扑。 LDO是线性电压调节器，在直流电压中不产生涟漪。尽管电源输入电压与输出非常接近，但该调节器仍将维护所需的输出电压。基于NMO和基于PMOS的LDO之间的详细比较，我们决定选择PMOS设计，因为与NMO相比，它不需要额外的充电泵。这里还提供了有关米勒电容如何增强总体设计稳定性的证明。并联多个通过元素，以增加通行网络的当前承载能力。
A stable low dropout (LDO) voltage regulator topology is presented in this paper. LDOs are linear voltage regulators that do not produce ripples in the DC voltage. Despite the close proximity of the supply input voltage to the output, this regulator will maintain the desired output voltage. Based on a detailed comparison between NMOS and PMOS-based LDOs, we decided to opt for a PMOS design because it does not require an additional charge pump as compared to NMOS. A demonstration of how Miller capacitance enhances overall design stability is also presented here. Multiple pass elements are arranged in parallel in order to increase the current carrying capacity of the pass network.
