A high-stability voltage regulator (VR) is proposed in this paper, which integrates transient enhancement and overcurrent protection (OCP). Taken into consideration the performance and area advantages of low-voltage devices, most control parts of proposed VR are supplied by the regulated output voltage, which forms self-power technique (SPT) with power supply rejection (PSR) boosting. Besides, the stability and transient response are enhanced by dynamic load technique (DLT). An embedded overcurrent feedback loop is also adopted to protect the presented VR from damage under overload situations. The proposed VR is implemented in a standard 350 nm BCD technology, whose results indicate the VR can steadily work with 5.5-30 V input voltage, 0-30 mA load range, and 0.1-3.3 μF output capacitor. A 2.98 μV/V line regulation and a 0.233 mV/mA load regulation are achieved with a 40 mA current limiting. The PSR is better than - 64 dB up to 10 MHz with a 0.1 μF output capacitor.

具有稳定性和电源抑制升压功能的瞬态增强型稳压器。

本文提出了一种高稳定度的稳压器（VR），该稳压器集成了瞬态增强和过流保护（OCP）。考虑到低压设备的性能和面积优势，建议的VR的大多数控制部件均由稳定的输出电压供电，这形成了具有电源抑制（PSR）提升功能的自供电技术（SPT）。此外，动态负载技术（DLT）增强了稳定性和瞬态响应。还采用了嵌入式过流反馈环路来保护所呈现的VR在过载情况下不受损坏。拟议的VR采用标准的350 nm BCD技术实现，其结果表明VR可以在5.5-30 V输入电压，0-30 mA负载范围和0.1-3.3μF输出电容器下稳定工作。2.98μV/ V的线路调节度和0。电流限制为40 mA，可实现233 mV / mA的负载调节。使用0.1μF输出电容器时，在10 MHz时，PSR优于-64 dB。
