1 / 8 page  Preliminary Datasheet LP2203 LP2203 – 01 Ver. 1.1 Datasheet Feb.-2008 Page 1 of 8 200mA,Dual Channel Ultra-Fast CMOS LDO Regulator General Description The LP2203 is a dual channel, low noise, and low dropout regulator sourcing up to 250mA at each channel. The range of output voltage is from 1.2V to 3.6V by operating from 2.5V to 5.5V input. LP2203 offers 2% accuracy, extremely low dropout voltage (80mV @ 150mA), and extremely low ground current, only 25µA per LDO. The shutdown current is near zero current which is suitable for battery-power devices. Other features include current limiting, over temperature, output short circuit protection. LP2203 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. LP2203 is available in fixed output voltages in the USP-6 package.
