SMIC 0.18μm 5v-3.3v Power Regulator
Overview
This IP is a Low-Dropout (LDO) 5V to 3.3V power regulator in SMIC 0.18μm 3.3V/1.8V Logic process. When it works in regulation region, the max rated output current is 200mA, and the current limit is about 300mA. When it works in dropout region, the typical dropout voltage is 133mV @IOUT=200mA. In addition, this particular physical IP has the scaled up version (110% scaled-up) of SMIC18_PRG_14B which is designed to be used in foundry’s 0.162um (90% shrink) process.
