Abstract: 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 m CMOS technology. The measured result reveals that the LDO0s power supply rejection (PSR) is about
􀀀58 dB and –54 dB at 20 Hz and 1 kHz respectively, the response time is 4 s and the quiescent current is 20 A.
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.
