This IP is a Low-Dropout (LDO) 3.3V to 2.5V and 1.2V power regulator in SMIC 65nm LL 1.2V/2.5V process. When it works in regulation region, the max rated output currents are both 60mA and the current limits are both about 120mA. When it works in dropout region, the typical dropout voltage is 150mV @IOUT25=60mA for 2.5V output.
