SMIC 0.13μm 5v-3.3v Power Regulator

This IP is a Low-Dropout (LDO) 5V to 3.3V power regulator in SMIC 0.13μm 3.3V/1.2V Logic process. When it works in regulation region, the max rated output current is 300mA, and the current limit is about 450mA. When it works in dropout region, the typical dropout voltage is 240mV @IOUT=300mA. This particular physical IP has the scaled up version of S13V33_PRG_09B which is designed to be used in foundry’s 0.11um (90% shrink) process.
