| 摘 要： | This paper introduces the design of a l.8 V low dropout voltage regulator （LDO） and a foldback current limit circuit which limits the output current to 3 mA when load over-current occurs. The LDO was implemented in a 0.18 μm CMOS technology. The measured result reveals that the LDO s power supply rejection （PSR） is about -58dB and -54dB at 20Hz and 1kHz respectively,the response time is 4μs and the quiescent currentis 20μA. The designed LDO regulator can work with a supply voltage down to 2.0 V with a drop-out voltage of 200 mV at a maximum load current of 240 mA.
