A Transient-Enhanced Voltage Regulator with Stability and Power-Supply-Rejection Boosting
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 volt...

description | 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. |
